Unfortunately, i couldn't find any historical document specifying a standard for supply crates size so i'll just make one up: * **1.5m** x **1.5m** (visual only) * **200kg** of max capacity The amount of such "standard crates" that can be loaded should then be calculated based on how many crates are needed to contain all the selected supplies ## Supply Trucks {% hint style="info" %} Part of this proposal has been edited from the initial one in the **1.1.0** version following [kamikazi21358](https://forum.warthunder.com/index.php?/profile/602350-kamikazi21358/)'s [feedback](https://forum.warthunder.com/index.php?/topic/459265-new-combined-warfare-game-mode-frontline/\&do=findComment\&comment=8211650) {% endhint %} ![(Edited Image) Supply truck carrying supplies in crates](https://485442258-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-Lm_FbBSwYyzdA_QlqOU%2F-LnRHAj_MDie2DmEVhfK%2F-LnRL4jS7q1xHQn7H9Tv%2Fsupply_truck_carrying_supplies_crates.png?alt=media\&token=3d5b048a-d904-4348-973e-081a631c2854) **Supply trucks** , due to their relatively high impact they can have on the battlefield, are limited to players with **no vehicles left** and **not enough spawn points** to spawn in vehicles of their **secondary line-up** They are entirely **unarmed** vehicles meant for support only, with **relatively high speed** but **extremely low survivability**. However, while they may seem pointless, they make **supply bases** even more impactful: * They carry supplies in crates, said crates can be **dropped** to be picked up later, either by another **supply truck** or by an **helicopter** * They are basically a **moving supply base** that can replenish itself by going back to the friendly **supply bases** * They can **help repairing**, but while they contribute **more** to repairs than **medium tanks, heavy tanks** and such, they contribute **less** than **light tanks** As they help friendly vehicles, supply trucks generate **score**, **rewards** and a moderate amount of **spawn points** ### **Resupplying Interface** The biggest challenge with this feature is to make resupplying a supply truck fast, easy and intuitive. To achieve that, this proposal suggest a categorized interface, giving global and local overviews: {% tabs %} {% tab title="Global Interface" %} ![The resupplying interface supply trucks have](https://485442258-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-Lm_FbBSwYyzdA_QlqOU%2F-LnRHAj_MDie2DmEVhfK%2F-LnRbmOFlvrardt00731%2Fsupply_truck_resuplying_modal.png?alt=media\&token=94ab32bc-2e61-425d-b8bf-22fcdcb088d5) {% endtab %} {% tab title="Local Interface" %} ![The resupplying interface with the "Light Tanks Equipment" category expanded ](https://485442258-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-Lm_FbBSwYyzdA_QlqOU%2F-LnRHAj_MDie2DmEVhfK%2F-LnRcH4UEQb5BW90VSCy%2Fsupply_truck_resuplying_modal_opened_light_tanks_equipment_accordion.png?alt=media\&token=cfd6208f-f89a-4a13-8898-f24a1009a0bf) {% endtab %} {% tab title="Detailed Local Interface" %} ![The resupplying interface with the "Light Tanks Equipment" category expanded with markings](https://485442258-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-Lm_FbBSwYyzdA_QlqOU%2F-LnRHAj_MDie2DmEVhfK%2F-LnRchhZP-dcrAFVBbWU%2Fsupply_truck_resuplying_modal_opened_light_tanks_equipment_accordion_with_highlights.png?alt=media\&token=d4b1d9e7-0f90-4619-9560-78f5775e8cb9) 1.

The maximum amount of shells a truck can carry is therefore limited to the maximum additional mass the truck can support > If we were to take the interface example where the maximum additional mass for this truck is said **800kg**, then it would only be able to carry a few of the **460mm** shells shown above, contrary to the example numbers Just like tanks, carrying the maximum amount isn't necessarily the best approach as: * Carried supplies are physically represented as **crates**, the more crates, the more visible a truck becomes, and the more crates, the higher chances of a detonation are * Because the **mass of the supplies** is added on top of the **mass of the truck**, the truck's power-to-weight ratio is decreased {% hint style="info" %} The interface can also be used to unload some of the currently loaded supplies. In the cases where a vehicle of a different class uses a gun caliber that is usually used in another class, the caliber will simply appear in both categories {% endhint %} ## Supply Airdrops {% hint style="info" %} This proposal was added as of the **1.1.0** version following [kamikazi21358](https://forum.warthunder.com/index.php?/profile/602350-kamikazi21358/)'s [feedback](https://forum.warthunder.com/index.php?/topic/459265-new-combined-warfare-game-mode-frontline/\&do=findComment\&comment=8211650) {% endhint %} Players will be able to spawn in a **transport plane** able to carry supplies if the following conditions are met: * If the player's **main line-up** is their **air line-up**, they may spawn as a transport plane as long as they **didn't spawned twice** in one yet * If the player's **main line-up** is their **ground line-up**, they can only spawn as a transport plane **once** and if they earned the required modest **50 spawn points** Ideally, transport planes should be based on historical model such as the american **Douglas C-47 Skytrain** {% embed url="" %} Supplies will be in the form of physical supply crates and should of course be limited to how much the plane can carry, ideally also based on historical references like the following: {% embed url="" %} Historical reference showing the C-47 could carry up to 6000 pounds of cargo (roughly 2721 kilograms) {% endembed %} The **standard crate** (as defined up above) being able to contain up to **200kg**, that means the **Douglas C-47 Skytrain** would, in-game, be able to carry up to **13 full crates and a half-full**. However, that is the theoretical amount. Planes, due to their high-speed flights nature, should **not** carry the maximum load possible to ensure the plane can still be controlled. This **margin of safety** should range between **10-20%** of the plane's max capacity. For the **Douglas C-47 Skytrain**, for example, i set the **margin of safety** to **500kg.** Meaning the **Douglas C-47 Skytrain** would be able to load up to **2221kg** of supplies, roughly **11 standard crates** {% hint style="info" %} A mass will need to be given to all modifications/equipments for this to work (smoke grenades, fire prevention equipment...) {% endhint %} ### Dropping Process ![(Edited Image) Transport plane air-dropping supply crates](https://485442258-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-Lm_FbBSwYyzdA_QlqOU%2F-LnVvJM6Mj8cgBxPh5R_%2F-LnVxSXgg6LtqGslMndn%2Flarge_plane_airdropping_supplies_nohud.png?alt=media\&token=09a41e47-fdf4-4bcc-84c8-d07e6d461759) The dropping process should follow the historical methods, more particularly the **Low-Velocity Airdrop** as defined by wikipedia: > The delivery of a load involving parachutes that are designed to slow down the load as much as possible to ensure it impacts the ground with minimal force. This type of airdrop is used for delicate equipment and larger items such as vehicles. {% embed url="" %} Each crate will therefore have a parachute, slowing its fall down enough to prevent damage to the fragile equipment it carries. This is an excellent way to balance it as well since the opposite team will have two ways to deny the other team's supplies: * Fire high-explosive shells at the crate to destroy it, or even regular armor piercing shell hoping that it will be enough to detonate the shells stored inside * Fire directly at the parachute while the crate is still relatively far from the ground to make the crate fall much faster, effectively destroying it on impact That second option would be even easier with accurate machine-gun fire so it would be possible to efficiently deny a team's supplies. {% hint style="info" %} While an obvious way to prevent the opposite team to shoot down the crates while they're in the air would be to drop them at low altitude, it would in fact result in an airdrop failure as drops from too low altitude wouldn't give enough time for the parachute to slow down the fall {% endhint %} ### Equipment In Crates - RTNC Method {% hint style="info" %} The **RTNC Method** (Real-Time Needs Calculation) term will be used to talk about the algorithm right below, but also more generally variants of this algorithm that also calculate the distribution of supplies in a crate based on how much they are needed {% endhint %} Unlike for supply trucks, players won't be able to select what they load, it will be calculated automatically based on the current needs of the team. As it's a multi-step process, i'm gonna write the raw algorithm as JS instead of a formula: ```javascript // Declare a variable that will be incremented while counting // That variable is arbitrary and gives the same value to everything, // Be it smoke greandes, high caliber shells, low caliber shells, fire extinguishers... let totalNeededSupplies = 0; // Declare a variable that will list all supplies needed and their amount let suppliesNeeded = []; // Iterate over each player in the friendly team for (const player in firstTeamMembers) { // Filter out un-deployed players, supply trucks and aircrafts if (player.vehicle && ["SPAA", "TD", "LT", "MT", "HT"].includes(player.vehicle.type)) { // Increment the variable for each smoke grenade/fire prevention equipment used for (const mod in player.vehicle.installedModifications) { // Filter out any modification that is not air-droppable // (Everything but smoke grenades and fire prevention equipment) if (["FPE", "SG"].includes(mod.type)) { // Declare a variable to keep the result in order to avoid // race-conditions by only calculating it once const amountNeeded = (mod.amount || 2) - mod.amountUsed; // Increment the variable by the amount of smoke grenades // Or by 2 if it's FPE as fire extinguishers always have two usages totalNeededSupplies += amountNeeded // Add the information to the detailed list suppliesNeeded.push({ type: mod.type, // Subtract the base amount by the amount of uses amountNeeded: amountNeeded }); } } // Merge ammunition type list from all of the vehicle's guns // (primary, secondary, MGs..) let allAmmoTypes = []; for (const weapon in player.vehicle.weaponry) { // Filter out weapons that may not be regular if (weapon.ammunitions) { // Merge this weapon's ammunitions list in the allAmmoTypes list allAmmoTypes.concat(weapon.ammunitions); } } // Iterate over all ammos and fill the lists for (const ammo in allAmmoTypes) { // Declare a variable to keep the result in order to avoid // race-conditions by only calculating it once const amountNeeded = ammo.baseAmount - ammo.currentAmount; totalNeededSupplies += amountNeeded; suppliesNeeded.push({ type: ammo.type, // (ex: 120mm_APFSDS) amountNeeded: amountNeeded }) } } } // Now that all the relevant data has been centralized // the global calculation can be done for (const equipment in suppliesNeeded) { // Give an importance level to the equipment by calculating what percentage // It represents against the total amount of supplies needed equipment.importance = equipment.amountNeeded / totalNeededSupplies * 100; } //We can now precisely know how much supplies of each ammo/equipments need to be loaded //Though perfect accuracy cannot be achieved due to the amount of decimals some //percentages are bound to reach //Because of that, how much of the equipment will be loaded will be as close as //possible to the exact percentage, but not any higher //(so the plane won't ever go over it's max cargo capacity, but usually lower) ``` So as an example, once we've done this calculation, let's say that 7% of the supplies needed are **120mm APFSDS** shells, then 7% of the plane's cargo space will be loaded with **120mm APFSDS** shells {% hint style="info" %} Note that for SPAA's ammunitions, the **amount of belts** is used instead of the total amount of singular ammos; Basically, the ammo belts are considered a **single shell** to more accurately represent the need of each ammunitions based on their size, and thus weight. As such, ammo belts are loaded in the crates as well instead of single ammos {% endhint %} ### Airdrop Rewards * Delivering an airdrop gives **100 silver lions** and **40 spawn points** if: * The airdrop is **successful** (not dropped at too low altitude to prevent crates from crashing) * The airdrop **is in the ground battle area** (what good would a crate be if the ground forces can't reach it) * For every friendly vehicles within a **100 meters radius** of **each** crate, **50** **silver lions and 10 spawn points** are given (as only rewarding based on if the ground forces use it would be unfair considering it's not up to the player) * Each friendly who refills **one shell or equipment** gives a **10 silver lions reward** (very small because of how much it can be if a friendly refills a lot) ## Helicopter-carried Crates ![A US Navy helicopter carrying supplies to an aircraft carrier](https://485442258-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-Lm_FbBSwYyzdA_QlqOU%2F-LmseGjHf8QzNTIDVNqn%2F-LmshzAxgACdzpIQD-gW%2Fa-us-navy-mh-60-knighthawk-attached-to-thechargersof-helicopter-sea-combat-7d7902-1600.jpg?alt=media\&token=2114dbd1-370c-4285-a4ba-63d06bf8de76) [Source image](https://picryl.com/media/a-us-navy-mh-60-knighthawk-attached-to-thechargersof-helicopter-sea-combat-7d7902) Unlike the dedicated transport planes, **any helicopter** can carry crates as secondary load but at the price of much less capacity than transport planes. The goal is to make helicopters more relevant (especially utility helicopters) as currently most of them are just food for the enemy anti-air ### Loading Crates Helicopters cannot carry nearly as much supplies as a transport plane. Because of this, it would be inefficient to have them load supplies like planes do.

Any crate dropped above **15m** has a good chance to break, forcing pilots to be careful when delivering supplies. * Helicopters cannot load crates on the battlefield if a vehicle is currently resupplying from it ### Gameplay **Helicopters were never meant to primarily fight tanks**, they are too slow and make too much noise to fight armored vehicles carrying heavy armament. In real life they are mostly used for **recon**, **transport** and **rescue** operations; **War Thunder** doesn't have **infantry**, making helicopters close to completely pointless. This feature aims to fight that by allowing them to be useful in the second lines, where they can deliver supplies to friendly vehicles and punish **light tanks** trying to sneak around. ## Differentiating Each Vehicle's Needs This wouldn't work too well if **supply trucks**, **helicopters** and **transport planes** didn't have at least a rough idea of who exactly needs the carried supplies; I've already mentioned the existence of a specific **marker** above the **friendly vehicles** that use some of the carried equipment, this same marker may be used to also indicate how much supplies a vehicle needs {% tabs %} {% tab title="Minor Needs" %} ![The marker above friendly vehicles with slow pulsations](https://485442258-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-Lm_FbBSwYyzdA_QlqOU%2F-LnWq7Xi_crN1DKaDM9L%2F-LnWsVM82GKSkmPYSjaZ%2Fneed_supplies_icon_slowest.gif?alt=media\&token=52202c90-5806-43c4-b391-669b722a6fb6) {% endtab %} {% tab title="Moderate Needs" %} ![The marker above friendly vehicles with frequent pulsations](https://485442258-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-Lm_FbBSwYyzdA_QlqOU%2F-LnWq7Xi_crN1DKaDM9L%2F-LnWsbPOPdJY3am90qqI%2Fneed_supplies_icon_medium_speed.gif?alt=media\&token=c572ef30-574a-42bc-8cee-efb256db77d7) {% endtab %} {% tab title="Major Needs" %} ![The marker above friendly vehicles with fast pulsations](https://485442258-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-Lm_FbBSwYyzdA_QlqOU%2F-LnWq7Xi_crN1DKaDM9L%2F-LnWseruKKdGFHf1HDNC%2Fneed_supplies_icon_fastest.gif?alt=media\&token=4cf2a2a7-501e-4a92-8d8c-f9d97a507886) {% endtab %} {% endtabs %} Both the marker above friendly vehicles (shown above) and the minimap markers pulsate. The faster it pulsates, the more supplies the vehicle needs. I've thought of using different colors for it at first, but i think this is a good way to do it that also works with people suffering from color-blindness
