I also take that 5-man biker squad w/
AB (as a troop unit) and Outflank them so they come in mid-late game. I've used them to contest an objective and as tank hunters. In both they work good. When I put them into
CC, they fair as well as any other 5-man marine sqd (though a little tougher).
I usually have my Khan Command unit Outflank as well and for whatever reason, the outflanking always confuses opponents. Do people normally not outflank?
And sadly enough, the last game I played against
IG, my Khan squad never saw
CC. I used them to form a block to keep 2 squads of sentinels, a squad of orgyn and some guards at bay. They didn't want to assault, and I strung my khan squad out so they could not get past. It worked, I won.
