| — In-game description |
30mm is a type of Shell for small cannons, useful against both structures and 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 400 Explosive damage at its center and decreasing amounts in a 2m radius.
It's effective against most structures but much less against very resistant ones.
It is effective against armored vehicles, however it needs to penetrate the armor in order to deal its damage. It can disable their subsystems.
It is cheap enough to be cost-effective to use against infantry and unarmored vehicles.
It does not stack in the player's inventory (1 per slot) except when wearing a Grenade Uniform or Heavy Ammo Uniform (stacks of 2 per slot).
Its weight is reduced by 33.3% (11.5% weight) with the Heavy Ammo Uniform and by 25% (12.9% weight) with the Grenade Uniform.
Usage
Users
It can be fired by the following infantry weapons, vehicles, and structures:
• Daucus isg.III 
• Callahan 
• Gallagher Brigand Mk. I 
• King Gallant Mk. II 
• T20 “Ixion” Tankette 
Production
| Structure | Input(s) | Output | Time |
|---|---|---|---|
 Factory (Heavy Arms) | 80 x Basic Materials  40 x Explosive Powder  | 1 Crate of 20 x 30mm  | 00:01:40 |
 Infantry Kit Factory (Heavy Munitions Foundry) | 45 x Construction Materials  220 x Explosive Powder 24 MW of power  | 10 Crate of 20 x 30mm | 02:30:00 |
 Mass Production Factory (Heavy Arms) | 80 x Basic Materials 40 x Explosive Powder | 1 Crate of 20 x 30mm | 00:16:40 |
Mass Production Factory orders must have at least 3 crates.
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 30mm 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.
