LOL I wouldn't really know. I went through IOBC (Infantry Officer Basic Course) as a mech-man but my duty station was the 9th Infantry Division, one of the last remaining "light" divisions in the army. For awhile I was a TOW missile platoon leader, but the TOWs are said to mean "Tired Of Walking!" Eventually we became the army's High Tech Test Bed and got to test the SEAL Dune Buggies and the now common Humvee.
A test and evaluation that sounds like fun!
All I got to test was proposed combat boots - by walking 500 miles on a test track at Fort Meade.
