For good reason I would say especially at the start of the war, the Russian infantry had zero AT capability apart from perhaps engineers or ski troop.
Pretty safe to run armour adjacent to troops therefore especially with tank panic for the age. I would risk running through woods or an urban enviroment. Give them Molotovs though & its a diffrent story clearing those woods is going to hurt a lot more.
Even a modern MBT needs to take care round a Molotov, would not count on it killing it but coud easily allow the attack that does.
Its a good all round weapon its "fault" being its unpredictability due to its nature, thats also why you treat it with respect.
In urban or woods if I was buying a force to win would go mol over grenade any day its worth the cost.
