Since the early 21st century, most NATO armies have settled on 155 mm (6.1 in) weapons as having a good compromise between range and destructive power whilst having a single calibre, which simplifies logistics; however some military forces have retained 105 mm (4.1 in) towed howitzers for their lighter weight and greater portability, including their rapid airlift and airdrop capabilities.
High-explosive anti-tank (HEAT) is the effect of a shaped charge explosive that uses the Munroe effect to penetrate heavy armor. The warhead functions by having an explosive charge collapse a metal liner inside the warhead into a high-velocity shaped charge jet; this is capable of penetrating armor steel to a depth of seven or more times the ...
The ammunition to be used was the 105 mm Fd Mk 2 ammunition used in the L13 ordnance of the gun equipment 105 mm L109 (better known as the "Abbot self-propelled gun"). This ammunition uses electrical instead of percussion primers and is an entirely different design from the US M1 type ammunition as used in the L5 pack howitzer.

Rifling is the term for helical grooves machined into the internal surface of a firearms's barrel for imparting a spin to a projectile to improve its aerodynamic stability and accuracy.

The 105 mm howitzer M102 is a lightweight towed weapon, which has a very low silhouette when in the firing position. The M102 howitzer fires a 33 lb (15 kg) projectile of semifixed ammunition and at charge 7 it will fire to 11.5 km (7.1 mi).
The LAPD used 40-millimeter launchers — which fire foam projectiles at more than 200 mph — in at least nine cases that involved firearms last year, a report says.
The project to develop a tank gun of 105 mm (4.1 in) in caliber was first started during WWII in order to compete with increasing heavily armored German tanks. After the invasion of Europe, the Ordnance Department believed there would be a need for heavily armored tanks equipped with powerful armament to break through fortified areas. [1]
