Anti-tank guns are direct-fire weapons designed to defeat tanks and other armored vehicles, typically by firing armor-piercing or shaped-charge ammunition at comparatively flat trajectories. They range from traditional towed anti-tank artillery pieces to recoilless guns (often called recoilless rifles) that trade a sealed breech for reduced recoil in order to keep the weapon portable. By the Vietnam War era, many armies relied more on portable recoilless weapons and rockets for anti-armor work, but gun-type anti-tank weapons remained useful for engaging light armor and for direct fire against bunkers and fighting positions.
DEFINITION & CHARACTERISTICS
“Anti-tank gun” is a functional category: it refers to a gun-type weapon intended to destroy or disable armored fighting vehicles using direct fire. Historically this includes towed anti-tank artillery, and in the post–World War II period it also commonly includes portable recoilless guns that filled similar roles with lighter launchers and shaped-charge ammunition.
- Common traits
- Role: Defeating armored vehicles with direct fire; also used for direct-fire support against fortifications, bunkers, and strongpoints.
- Typical cartridges: Gun projectiles optimized for armor defeat (armor-piercing shot, HVAP/APCR, or shaped-charge/HEAT), with some systems also firing HE or other rounds for general targets.
- Typical fire modes: Single-shot, crew-served direct fire; rate of fire depends on crew drill, ammunition handling, and weapon type.
- Typical feeding: Breech-loaded fixed or semi-fixed ammunition for towed guns; many recoilless guns use fixed rounds with vented/perforated cases (design varies).
- Common engagement ranges: Generally intended for direct-fire engagements out to practical line-of-sight distances; effective armor defeat depends on ammunition type and target armor.
- Notable tradeoffs: Strong anti-armor effects for relatively low cost and simplicity versus crew vulnerability, setup/aiming requirements, and (for heavier guns) limited mobility; recoilless systems gain portability but can have significant backblast and signature.
HISTORY
Specialized anti-tank guns emerged as armies responded to tanks with dedicated direct-fire weapons and ammunition designed to penetrate armor. Over time, improvements in armor and the development of shaped-charge (HEAT) munitions influenced anti-tank gun design and doctrine, and many forces sought lighter systems that could still deliver effective anti-armor effects. In the postwar period, recoilless guns became a common solution for portable anti-armor firepower, using venting to reduce recoil enough for man-portable or light-vehicle mounting.
In the Vietnam War era, gun-type anti-tank weapons were present, but their employment often reflected the conflict’s mix of limited early armored encounters and heavy emphasis on infantry combat in cover. U.S. Marine Corps references describe the M40 recoilless rifle as a portable, crew-served weapon intended primarily for anti-tank use and also employed in an anti-personnel role (including flechette ammunition). Communist forces also fielded a variety of anti-armor weapons, and period Australian War Memorial photography documents captured 57 mm recoilless rifles among VC weapons recovered during the Battle of Long Tan—illustrating the kinds of gun-type anti-armor weapons that appeared in theater.
