| — In-game description |
The 68mm is a type of anti-tank Shell used by many cannons and useful against armored vehicles.
Description
It travels instantly and in a straight line.
It explodes on contact or if it reaches the maximum range of the cannon firing it.
By default its explosion deals 600 Armour Piercing damage at its center and decreasing amounts in a 1.5m radius.
It is not very effective against structures and awful against very resistant ones.
It is very effective against armored vehicles, however it needs to penetrate the armor in order to deal its damage. It has a 50% bonus to its base penetration chance. It can disable their subsystems.
It is very expensive and thus not cost-effective to use against infantry.
It does not stack in the player's inventory (1 per slot) except when wearing a Heavy Ammo Uniform (stacks of 2 per slot).
Its weight is reduced by 33.3% when wearing a Heavy Ammo Uniform.

Production
| Structure | Input(s) | Output | Time |
|---|---|---|---|
 Factory (Heavy Ammunition) | 120 x Basic Materials  240 x Explosive Powder  | 1 Crate of 20 x 68mm  | 00:03:20 |
 Infantry Kit Factory (Heavy Munitions Foundry) | 130 x Construction Materials  1320 x Explosive Powder 24 MW of power  | 10 Crate of 20 x 68mm | 05:00:00 |
 Mass Production Factory (Heavy Ammunition) | 120 x Basic Materials 240 x Explosive Powder | 1 Crate of 20 x 68mm | 00:33:20 |
Mass Production Factory orders must have at least 3 crates.
Due to its high cost, it is recommended to use the Mass Production Factory whenever possible to produce 68mm, as it saves Explosive Powder.
Storage
It does not stack in structure or vehicle inventories (1 per slot) except in ammo slots dedicated to it (varying stack sizes). It can be stored in stockpiles of Bases (32k max).
Crates of 68mm can be directly submitted to any item stockpile that accepts that item to transfer their content.The crates can also be stored in the crate stockpiles of Storage Depots (1000 public, 100 per Reserve Stockpile), Seaports (1000 public, 100 per Reserve Stockpile), Shipping Containers (60), or Storage Ships (1000).
It can be transported by almost any vehicle with inventory slots. However it is much more efficient to transport it in bulk amounts as crates, either delivering them to a Base's stockpile with a Truck or to a crate stockpile with shipping vehicles carrying Shipping Containers.
