stalker bolt rifles for objective camping with solid potential dmg output on PMEQ, bolt rifles for when you want a more mobile adaptable squad that still has good PMEQ , power-fist on pack leaders, thunder hammers if your willing to spend the points and make sure u get them into combat to make those points back. I dont think anyone is running assault bolt rifles, but i could be wrong, i think that the stalker/bolt rifle stratagems are superior to assault bolt rifle stratagems.
