The Battering Ram is a mobile Anti-Tank field gun firing 68mm armour-piercing rounds.
— In-game description
The AA-2 Battering Ram (also known as a Field Anti-Tank or FAT) is a ColonialField AT Gun equipped with a 68mm main cannon. Its most distinctive feature is the low frontal plate, which barely covers the top part of the cannon's mount.
The AA-2 Battering Ram is specifically designed to attack enemy vehicles, as its main shell, the 68mm, is specially designed to penetrate enemy armor.
Due to 68mm being an AP round, it has a higher chance of penetrating armor, and can disable subsystems easier compared to 75mm rounds. Targeting enemy vehicle's subsystems is highly recommended.
All push guns, by their nature, are one of the most vulnerable vehicles in the game in terms of crew protection. They are exposed to the enemy, making them susceptible to all enemy fire. Due to push guns requiring both crew members to move them, the death of a single crew member could result in the push gun being lost. Due to this, it is recommended to only lock the gun when it looks like enemy infantry are going to overwhelm you and can steal it. This tactic is vital if a push gun is decrewed, as it allows a friendly soldier to quickly man it and drive it back to safety.
Push guns have a visibility mechanic, which allows it to operate differently compared to regular vehicles. Similar to infantry, they are affected by vision, meaning their movements cannot be seen unless it is within your line of sight. Due to this, they can hide behind structures, or even bushes (depends on how big the bush is). It's also affected by the time of day, with nighttime making it possible for push guns to become invisible to the enemy if you're far enough from them. Keep in mind that if the enemy decides to illuminate your position, this will expose it until the flare dies out. The push gun's position will be exposed anyway if the crew decides to fire its main armament.
Unlike their real-life counterparts, Field Weapons are mobile weapon platforms and do not need to be emplaced in order for them to be used
The Spade in the back used to anchor the gun and prevent the weapon's recoil from moving it too much is purely aesthetic
