Try this 180 Allied army against your friend’s Vet Tiger build:
5 x SE = 45
1 x SE capt = 11
1 x Quad 50 = 10
1 x Resourceful Hero = 8 (reluctantly submitted)
1 x Vet Sherman Rhino = 26
1 x Pershing = 65
3 x Flamethrower = 15
The idea is to get the SEs around it at the right time and try to disrupt it, hopefully saving the hero for when you lose a tank…which you will. This build looks to the support that the Tiger will certainly have. I went for the Pershing and a Quad 50 because at 180 pts, you can’t rule out a Stuka or two.
Things will, of course, heavily depend on the map and available cover. Eh, give it a shot.
And yes, DL and Grim are right. Play w/ an objective when you can. In lieu of a cooperative opponent, try the above and let me know how it works out if you would.
