Or avoid BS like that entirely. I have 2 ATGs, maybe 3; spam just promotes sloppy play and poor ATG micro. 2 = i micro them well or lose. I <3 shermans, medium tanks are the shit vs. anything other than pantherspam. SE...yeah, on Allied Attack thats gonna be BS. Spartan had 4-6 muni HTs with the concentration mine upgrade. That was shite powerful since they slow tanks, inf, are incindiary, do more damage on explosion then regular mines anyways etc...phew, just a really good ability. Add defensive coys in and yeah, allies are Fked. Oh well, so goes the 'fun' of CoH xD allies will find some ghey way to beat that defense. Callyspam or something.
Saturation minefield doesn't really do any damage to tanks now that as far as I can tell they no longer put butterfly mines in the mix, it's just firecracker and vehicle slow mines now, just as a fyi. The fire damage on can sometimes engine dmg weakened light vehicles and tank destroyers but it will do pretty much nothing to heavier tanks.
