Historically, howitzers fired a heavy shell in a high-trajectory from a relatively short barrel and their range was limited but they were slightly more mobile than similar size field guns. Since the end of World War II , howitzers have gained longer barrels and hence increased range to become gun-howitzers .
Adolf Gun, a Nazi German cross-channel firing gun. The formal definition of large-calibre artillery used by the United Nations Register of Conventional Arms (UNROCA) is "guns, howitzers, artillery pieces, combining the characteristics of a gun, howitzer, mortar, or rocket, capable of engaging surface targets by delivering primarily indirect fire, with a calibre of 76.2 mm (3.00 in) and above".

Most nations use rapid-fire cannon on light vehicles, replacing a more powerful, but heavier, tank gun. A typical autocannon is the 25 mm "Bushmaster" chain gun, mounted on the LAV-25 and M2 Bradley armoured vehicles. Autocannons may be capable of a very high rate of fire, but ammunition is heavy and bulky, limiting the amount carried.
The M2 machine gun or Browning .50 caliber machine gun (informally, "Ma Deuce") [13] [14] is a heavy machine gun that was designed near the end of World War I by John Browning. While similar to Browning's M1919 Browning machine gun, which was chambered for the .30-06 cartridge, the M2 uses Browning's larger and more powerful .50 BMG (12.7
The use of gabions with cannon was an important part in the attack and defense of fortifications. Gustavus Adolphus of Sweden emphasized the use of light cannons and mobility in his army, and created new formations and tactics that revolutionized artillery. He discontinued using all 12 pounder—or heavier—cannons as field artillery ...

The target is initially defined by the gunner, who places a configurable frame around it. The tracker then uses algorithms to compare that region of the frame based on image, geometric, and movement data to the new image frames being sent from the seeker, similar to pattern recognition algorithms. At the end of each frame, the reference is updated.
The Heckler & Koch HK417 is a battle rifle designed and manufactured by Heckler & Koch. [1]Being the larger caliber version of the Heckler & Koch HK416, and chambered for the 7.62×51mm NATO rifle cartridge, it is intended for use where the penetrative power, stopping power, and range of the 5.56×45mm NATO HK416 would otherwise be insufficient.
