Right now, I am mainly playing against my friend Chaos, his havoc squad's 4 auto-cannon tank hunters are a total nightmare to my mechanise army. If he gets the first turn, he'll always destroy/immolise one of my rhino and destroy/immolise one each turn after that.
What's the best way to deal with this autocannon tank hunter (8 shot krak missile equivalent)?

I always try to take 2 rhino/1 immo, or 3 rhinos in a 1000 pt game, but they always go down before they could do anything.. and that's 150 pts plus upgrades gone.. and leaves my army foot-slogging through the 24'' of open field against a semi-shooty chaos army. Help please :cry:
Oh and one more problem.. how can we deal with front armor 14 chaos predator/land raiders without lascannon? Surely it cant be a front armor 11 immolator with twin-linked multi-melta .. or foot-slogger with meltas, they'll never reach it/catch up to it before they get obliterated
