full-auto. there was no concept of individual accuracy in soviet doctrine, but rather superior firepower and enemy suppression en-mass to quickly advance. very little training was provided to regular grunts as far as target shooting or shooting in general. each squad had a designated marksman who would move with a squad and engage high value targets.
at least in the late 70s there were TWO range days allocated per year (spring and fall) to practice live fire and live firearms handling. but at least we had lots of marching with the guns and cleaning (once a week) rest of the time in between
this obviously only true for regular conscript troop. specialized unit folks were training quite a bit more actually.
