Well since you have CAS and Spearhead I would probably take CAS over spearhead 8/10. It allows you to afford lmgs, tellers, and quick at/anti-inf strafe at a moments notice. Only problem is figuring out when to use them/know if you want to tech up or not. Usually sticking with just t1 and t2 is your best bet. Only problem is the fact that you wont have any armor on the field to work with really. However, you will have a large inf based army that should be able to take on any type of enemy inf-spam with ease. Use the strafe to pin enemy blobs trying to flank/overwhelm you. If you're vs a Soviet player get at least 2 paks and 1-2 shrek squads and lay down 2-3 tellers. If vs USF simply get 1 pak out and 1-2 shrek squads, and lay down 2-3 tellers. Rest of your army should consist of 4-6 grens with at least half equipped with lmgs, 2 mgs, 1 mortar, and a hf(optional). Get at least 1 muni cache up(preferably on cutoff) to help maximize ammo intake, prioritize at least half of the map which is most open/easier to defend and branch out from there easily, leave one mg on the side of the map where you are branching out of whenever possible. Once heavy armor hits the field concentrate on taking it out by baiting it into a pak wall with shreks and then using the at strafe from behind to bring it down to 20-30% health instantly(angle the plane to come from behind the vehicle as it usually will be micro'd backwards). Eventually you will bleed your opponent out mp wise pretty easily and take the whole map/win. With Spearhead just do everything above but get a mortar hf out instead of a mortar and save fuel to spam dbl Tigerz and pew pew pew your way to victory.
