I'm under this PLT headed by an E-5 and I'm conducting P.t. with them until I PCS in 3 mos. So this Thursday morning, we were ruck marching and he calls me by my last name without addressing me and tells me [an E-6] to move up. But I told him i'm fine because I am staying back with a Soldier lagging behind. Minutes later he lunged at me bumping me off balance, but had he not grabbed me I would have fell on the ground. Of course we exchanged words. Question: I say this is assault, but our XO (who was there) and our 1SG & CPT, (who I told) said yea will talk about it on Monday. Sounds like they don't really care. Should I take this higher?
