A retired friend of mine told me the same thing,. Well he said they still use them at some bases. More for training as the enemy in mock battles, or they are down range for target practice by the bigger tanks and heavy artillery.
By the time I got to FT Benning at the end of my tour of duty, they were used for the tanker squad, because funds were low. As a scout I was relegated to a jeep with a 50 caliber attached, like the old Movie Rat Patrol, since I was not a tanker. My MOS was 11D10R8, which is a scout with special training for the missile system they used on the tank.
It was primary a scout vehicle though, thus the designation as reconnaissance assault vehicle, and the need for speed to get out of trouble before your spotted by big guns, because it has no armor.
After 6 Months they found out I knew all about the Sheridan and so I was back put on it. Which was OK, but it meant I had to spend a lot more time in the Motor pool, where as before I was able to drive all over base in my jeep escorting lieutenants and captains.
Yet I was able to play with the tank a a gunner a few more times. I even came in at the top 5 in qualifying as my Platoon Sgt as my TC. To this day IO look back fondly to my time on that baby.
OHH, the stories I could tell.
Well, go ahead and tell us more.
I would like to read your stories.
