I was on a Rome Plow and some of our guys were good at putting the track back on with the stinger of the blade. All the driver had to do was look at a mud puddle and get stuck. Usually a couple Rome Plows would open the jungle and a couple tanks would follow. We cleared 100,000 acres of jungle and the tanks usually did not get too close.
What was the M- designation of the Abrams tank?
M-1 Abrams Main Battle Tank - 105mm main gun
M-1A1 - 120 mm smoothbore cannon
M-1A2 - All kinds of electronic and fire control upgrades. Its a real whiz-banger from the gunners seat or T/C position.
Abrams is the M1 (and M1A1, M1A2, M1A2 SEP, etc).
