in a resonabale szeanrio ther would be more than that...a 6pdr, piats, sniper, aec, etc....
the aec would stunshot one stug, outmanourver the other and kill it and than kill the other stug...and would dmg a p4 to half health
And where are PAKs and Grenadiers with Fausts to cover the StuGs from getting circle stafed by AEC? Isn't that reasonable? Either way, the fact that a TD that costs 50 fuel more has to use over 100 munitions to beat a StuG assuming both are in a straight up duel firing at each other says all it needs to.
