Went from Airborne Infantry to Armour , got tired of walking everywhere I went. Started out in the M60A1 , moved up to the M1 Abrams , Talk about a KILLING MACHINE !!! We called it the "Jeti Tank" right out of Star Wars. Hauling ass across country , gunner locked on target , laseing, FIRE , ON THE WAY , TARGET , from a mile or more away !! What is the down side ? Throwing a track anywhere , but in feet of mud in Mopp gear really sucks , have spent more than 10 hrs putting a track back on and cleaning the bitch up to turn in to the motor pool. For some reason the motor pool guys want them SPOTLESS ! Hell its a tank , its not the kitchen counter. O'I forgot to say how cool it is running over BIG trees, and old buildings and just about anything that gets in your way.
