I would suggest breaking up your sentinels and switching 2 of them over to HF if your going to drop troop. Deep striking a HF right next to anyone, is a ugly thing, 2 is death for just about anyone. Also I have always found that if you don't have some firebase for the enemy to think about he will focus on your dropping troops. maybe a AT ML team and HB FS team along with that one platoon with HB then every thing else deep strikes. Also Deep stike your platoonHQ, NOT YOUR CHQ keep him alive to give LEadership push. Only 1 IC is needed in this army. Drop the plasma pistol on the vets. Get Iron disapline for your officers. Your officers are the keep to the battle, Also I never give heavy weapons to my HQ cause they are always moving. If you want the Hvy bolter effect, give 4 GL that should put a hurting on any vehicle, and it has effect range 30"(move 6 shoot 24). These are things that I have tried and found that work in my drop troop army (w/carapace armor, the 2nd best doctrine)
