Some modern tanks can fire guided anti‑tank missiles from their main gun barrels, offering longer range and higher accuracy than conventional shells.
Advantages include engagement of targets 5–8 km away, improved precision at long distances thanks to laser or semi‑automatic guidance, the ability to hit low‑flying or hovering helicopters, and the use of a two‑stage warhead to defeat reactive armor.
Disadvantages are slower velocity compared to APFSDS rounds, the need to maintain a sight on the target until impact in many models, higher susceptibility to active protection systems such as Trophy and Arena, and a higher cost than standard tank ammunition. Consequently, APFSDS shells remain the best choice for close‑to‑medium range tank battles, while barrel‑launched missiles provide crews with extended reach against helicopters, fortifications, and armored vehicles.
