geologic time scale.
i got this answer from a final in my science class
Hamburger Hill was the 101st Air Cavalry Division and the 1st Cavalry Division, both Army units.
Periods
The 34th "Red Bull" Infantry Division was one of the earliest units to arrive in England. Also the 1st Armored Division arrived there and transitioned to the newer Sherman tanks. Both of these units were the first to be sent into combat in North Africa.The 1st Infantry Division arrived early in UK, I believe.Since the 34th Division fought continually in N. Africa, and Italy, it accrued more time in combat then the 1st Infantry Division, which was taken out of combat for training in preparation of the D-Day landings.Custermen
They were called legions, with six to ten thousand men, the equivalent of a division in a modern army.
The US Army changed the organization in 1939 to reduce the size of the Infantry Division from the size it was in WW1.Infantry Division - 15,000 menAirborne Division - 9,000 menThe size and organization of divisions vary for each country: Britain, Germany, etc.
