I discovered yesterday that as assault you can lay 7 C4 charges. Use explosives perk for more C4, put ammo pack on ground, place 4, get some from ammo pack, place, repeat. Detonating makes them all go boom. That is, if you like being useless (I do sometimes because the destruction and physics is just a lot of fun to play with).
