Remember when Penals cost 360mp and would beat grenadiers in long range & close range and their satchel AOE was 10 instead of 6, people still said that they were useless with 30 reinforce per man, when Relic dropped their cost and made them cost less mp, people were happy, but now its back to penals being total waste of a unit
*Edit* Penals also can self destruct with a satchel if you start throwing it when a tank tries to crush you, it will instantly explode, same with AT grenades/Panzerfausts
