As far as I recall the Soviet early war TH teams have molotovs usually, which means they are useless at taking out anything other than open-tops. As they will always throw the cocktails before they resort to grenades.
Later they get improved weaponry, but may still come with molotovs? Which again may be their first choice of weapon still?
German TH teams are generally better, but once sherks appear, I don't bother them. Maybe I should, as some of the hardware they tote certainly takes out tanks. And with 2 MP40s they can pack a bit of close range punch in the woods, providing good scouting units.
Early on, Russian AT rifles are okay for HTs and thin armour. And can provide a nuisance factor.
