Basically don't go pure LAMI (will turn the game into a disaster whenever some serious mobility will be required), use a mix of LAMIs and CAPs, if points allow add a minimised pathfinder platoon and give sergeants the dogs to sniff out camouflaged bugholes. A twin-firestorm grizzlie captain and (if points allow) minimised exo platoon can help too with adding some punch.
One Slingshot w/Heavenly Mercy payload is an absolute must in this campaign - just to recycle some men.
And giving the captain the sense presence trait will be very usefull, especially as long as multiple reactons are still legal.
