All right, if it's a history lesson you want, it's a history lesson you'll get. The following is a list of all of the major U.S. ground combat forces that fought in Desert Storm: 1st Cavalry Division, 1st Infantry Division (Mechanized), 1st Armored Division, 1st Marine Division, 2nd Marine Division, 2nd Armored Cavalry Regiment, 3rd Armored Cavalry Regiment, 3rd Armored Division, 24th Infantry Division (Mechanized), 82nd Airborne Division, 101st Airborne Division, and the U.S. Army Special Forces.
Hmmm, not a Reserve or Guard unit in the bunch. Still laughing?
