Tanksoldier: Do they still use the 120mm HEP and Flechette rds as part of the basic combat load? The original M1's I trained on had selector switches for the computer to calibrate for these loads. 'Course that was the older 105mm smoothbore. Lessee if I remember the terminology: Armor Piercing, Fin Stabilized, Discarding Sabot is the main gun tank round, correct? APFSDS right?
