Here Are All of the Advanced Guns the Army Wants
So many small arms.
Key point: The Army needs replacements to many of its weapons and is looking for something high-tech and reliable to fill those gaps.
The U.S. Army is testing submachine guns in advance of what could be its first official sub-gun in more than fifty years. The Army’s Sub Compact Weapon System program is scouting the field for a weapon that delivers assault-rifle level firepower in a platform smaller than the M4 carbine. The gun is destined for the service’s Personal Security Details but could be expanded to wider use throughout the Army.
The submachine gun was first invented in World War, a product of trench warfare. European armies on the Western Front saw the need for a compact, high-firepower weapon useful for clear trenches of enemy troops, a task the bolt action rifle was ill-suited for. The result was a wave of fully automatic, compact weapons with shoulder stocks, typically firing pistol caliber ammunition.
Submachine guns continued to be popular in World War II, where they were useful in jungles and fighting in built-up areas such as cities. After the attack on Pearl Harbor, the U.S. Army went to war with the famous M1928A1 Thompson submachine gun. The Thompson, made famous by police and gangsters like during the 1920s and 1930s was well-liked, though complicated and slow to mass produce.
