| — In-game description |
20mm is an anti-tank caliber Magazine. It is primarily designed to damage armored vehicles.
Description
By default its bullets deal 150-225 Anti-Tank Kinetic damage.
It does not deal any damage to structures and is very mediocre against unarmored vehicles.
It is very effective against light armored vehicles and somewhat effective against heavy armored vehicles (Tanks, Field Weapons). Its rounds cannot be deflected by Tank Armor and they damage the armour's integrity. They cannot disable Vehicle Subsystems.
It is good at suppressing infantry and vehicle gunners.
20mm bullets use green tracers.
It does not stack in the player's inventory (1 per slot).

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 20mm 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.
Trivia
- Prior to Update 0.44, 20mm ammo was known as 13.5mm ammo.
