Anti-tank guns are field pieces, modern cannons designed to destroy enemy tanks with armor piercing shells. Anti-tank guns are not very mobile on their own, as they must be dragged about by their crews. With only a thin gun shield for protection, anti-tank guns require a mix of surprise and proper placement to be effective. Anti-tank guns with High-Explosive (HE) rounds can be effective against infantry, but are often better left hiding to wait for enemy armor.
Anti-Tank Gun Tactics
Anti-Tank guns can usually deal with a single enemy tank, especially if they get the first shot from ambush, but they can rarely survive the return fire from multiple enemies. To this end it is often best to place anti-tank guns in cover and with long, narrow fields of fire, such as aiming down a long, tree lined road. This allows the gun to shoot at enemy tanks at longer ranges, where it is harder for them to be spotted, without being subject to return fire from enemies elsewhere. Once an anti-tank gun has been spotted the enemy will usually make it a priority target, so you may want to keep a towing vehicle handy to quickly move the gun to a new location.
