3/4's the same. The 152mm Sheridan main guns, used primarily in Vietnam, fired FULLY combustible shells, nothing came out of the breech after firing, except smoke. The Abram's 120mm ejects a back cap after firing.
The US Lost somewhere between 50-100 M1 Abrams where as the British lost 0 Challenger 1 Tanks.
Although those two types of tanks never clashed directly in Vietnam (M48 Pattons and PT76s did however), both the Sheridan and PT76 tanks are comparable adversaries. They are both similar in size and weight, and both are fully amphibious.
as far as i know, male tanks used cannons (guns firing explosive shells) and female tanks used machine guns with conventional rounds
During the Vietnam War, the US Army/Marine Corps M48 Patton tanks could travel about 20 mph. The brand new M551 Sheridan tank (which landed in Vietnam in 1969) could hit 45 mph. The Sheridan's hull was built of aluminum; it's turret & main gun were constructed of steel.
Because it was made of aluminium, which is a much lighter metal that allows the whole thing to be airlifted using a mighty Bell UH-1. Oh, and by the way. Viet Nam and WWII are different wars, so be careful with your category choices.
The M551 Sheridan aluminum tanks used in Vietnam were called she's; but the Sheridan tank itself was named after a "he." General Sheridan, US Army, War of the Rebellion (Civil War).
The M551 Sheridan had an aluminum hull, but almost all tanks have had steel hulls.
Vietnam War tanks such as the M48 Patton and M551 Sheridan tanks had roughly 300 gallon fuel tanks.
Most likely the M1 Abrams
The M551 Sheridan aluminum tanks were largely retired after the Vietnam War. A few remained in service in Abn units and training areas.
those arrows are to separate the tanks from other companys, since all m1 abrams look the same the arrows tell what company that tank belongs to. you will see different style arrows on tanks of different companys
During WWII, US tanks burned gasoline for fuel; during the Vietnam War US Patton and Sheridan tanks used diesel for fuel.
Besides the US, the armies of Egypt, Saudi Arabia, Kuwait, and Australia.
Australians drove Centurion tanks. Americans drove Patton and Sheridan tanks. The ARVN drove M41 Walker Bulldog light tanks; and the enemy, the NVA, drove PT76 Amphibious light tanks and T55 medium tanks.
The United States has several types of military tanks in its inventory. Some of the main types include the M1 Abrams, M2 Bradley, M3 Bradley, and M109 Howitzer. Each of these tanks serves specific functions and is used for various combat situations.
Up until the Vietnam War, US tanks were built from steel. With the one exception of the M551 Sheridan light tank (17 tons); which was officially designated as the Armored Airborne Reconnaissance Assault Vehicle and first fielded in January 1969 directly into the Vietnam War. The Sheridan had an aluminum hull with a steel turret and 152mm main gun. It was the only US tank that could swim and was air transportable. The M551 also fired a caseless tank round, no empty shell casing ejected from the breech after firing, as they did in the M48 Patton tanks after firing. After Vietnam, the M1 Abrams MBT (Main Battle tank) entered service in about 1983. The Abrams (named after the last US commander in Vietnam, General Creighton Abrams) is constructed from classified man made materials similar to the Kevlor helmet and protective body armor worn by current troops; as well as other metals. The M1 also fires a semi-caseless tank shell, not as caseless as the Sheridan did, as a metal cap ejects from the breech after firing in the M1.
Ships, flat bed trucks, and trains. Light tanks such as the Vietnam era M551 Sheridan (built of aluminum) could be transported by air.
