During the Vietnam War, US Army "Armor" Battalions (Tank Battalions) consisted of approximately 53 to 57 M-48 Patton tanks. 17 tanks per company; three companies per battalion, with two or more tanks in HQ Company. Armored Cavalry Squadrons consisted of approximately 27 to 30 tanks (Patton and later Sheridan tanks). Basic rule of thumb is two or more battalions made up a brigade, two or more brigades made up a division, and two or more divisions made up a corps. AFTER the Vietnam War, the US Army switched from a 5 tank platoon/17 tank company to a more "metric" orientated organization...along with the new 9mm service pistol (which replaced the Army .45). As of 2011, the US Army and US Marine Corps have a total of about 4500 M1A1 and M1A2 tanks in service, with approximately the same number of M1 tanks in storage. The US Army operates about 80% of the total US tanks.
