Because it is charging an su85, for example?
Then you're using is as incorrectly as it can possibly be, because that's easiest way to lose a tank against any faction.
The scouting - you must rush su85 as it outranges your tanks. It is enough that there is a relatively cheap 60muni upgraded squad around and you are dead. Scoutning will not help here. It just prevents you from rushing completely. Ant this is exactly the problem - Soviets have this super powerful nuke at grenade while other factions don't, and have to pay more for similar goodies. With Soviets there are too many relatively cheap things on their infantry that will make it impossible to rush long range tds.
If you get hit by SU-85, regular AT nade will do the same, and since you're clearly charging blindly and forward, you will not be fully healed.
Since you're rushing without scouting or sweepers, you can hit a mine.
You can run into ATG.
You can run into med tank protecting it.
Everything in your scenario boils down to what I've said - reckless, stupid, suicidal play.
AT satchel are not your problem, bad decisions and wrong approaches are.
