Here's some help, don't do it. Tactics and HtH don't mix mostly because in the later mission, when you run into super mutants, they'll cut you to ribbons with their SAW's and Browning M2's. If you want to go HtH you need at least, imo, a medic, a sniper and a big gunner/grenadier with you. The medic for healing, the sniper for softening up the opponent and for picking off weaker ones and the big gunner/grenadier for crowd control but solo

, to though.
