106-620: In early 1963, the M72 LAW was adopted by the U.S. Army and U.S. Marine Corps as their primary individual infantry anti-tank weapon, replacing the M31 HEAT rifle grenade and the M20A1 "Super Bazooka" in the U.S. Army. It was subsequently adopted by the U.S. Air Force to serve in an anti-emplacement and anti-armor role in airbase defense. In the early 1980s, the M72 was slated to be replaced by
212-414: A backblast of gases around 1,400 °F (760 °C). The rocket propels the 66 mm (2.6 in) warhead forward without significant recoil. As the warhead emerges from the launcher, six fins spring out from the base of the rocket tube, stabilizing the warhead's flight. The early LAW warhead, developed from the M31 HEAT rifle grenade warhead, uses a simple piezoelectric fuze system. On impact with

While closed, the outer assembly serves as a watertight container for the rocket and the percussion-cap firing mechanism that activates the rocket.

Despite early problems, it was a success and was copied by other countries. However, the bazooka had its drawbacks. Large and easily damaged, it required a well-trained two-man crew. Germany developed a one-man alternative, the Panzerfaust , having single-shot launchers that were cheap and requiring no special training. As

Following the Civil War, the U.S. Army had the mission of containing western tribes of Native Americans on the Indian reservations . They set up many forts, and engaged in

Some branches, such as Special Forces , operate similarly to functional areas in that individuals may not join their ranks until having served in another Army branch. Careers in the Army can extend into cross-functional areas for officers, warrant officers, enlisted, and civilian personnel. Before 1933,

By 1989 Germany was nearing reunification and the Cold War was coming to a close. Army leadership reacted by starting to plan for a reduction in strength. By November 1989 Pentagon briefers were laying out plans to reduce army end strength by 23%, from 750,000 to 580,000. A number of incentives such as early retirement were used. In 1990, Iraq invaded its smaller neighbor, Kuwait , and U.S. land forces quickly deployed to assure

At that time, its nearest equivalents were the Swedish Pskott m/68 (Miniman) and the French SARPAC . The increased importance of tanks and other armored vehicles in World War II caused a need for portable infantry weapons to deal with them. The first to be used (with varying successes) were Molotov cocktails , flamethrowers , satchel charges , jury-rigged landmines , and specially designed magnetic hollow charges. All of these had to be used within
