This mechanized infantry unit is too weak, so comparatively, these few tanks are performing too strongly.
The moment the rocket launcher gunners opened fire, the tank cannons were able to respond immediately, it's not a matter of aiming accuracy but the tank cannon's swiveling isn't that fast, hence, the first two tanks were firing preemptively, targeting the threatening positions they anticipated before opening fire.
For the tank cannons to have such accurate firing while the infantry carried on the armored vehicles is so unskilled, there definitely must be an issue.
Cannon fodder also has its value, no one purposely sends many men to certain death just for the sake of it.
In this confrontation that could be considered as genuine and direct, the role of cannon fodder, of course, is only to attract attention for the real elites and relieve the pressure.
