IMHO you should avoid pogroms until you have, at the very least, warrior armor, 6 gals with decent stats, guns powerful enough to kill a regular enemy in a single turn, a decent melee weapon on every gal, about two grenades that do different damage types on each gal and medikits on everyone. Move your gals in pairs so one can heal the other if needed.
With this, you can do bandits, humanists and maybe spartans, but your gals are gonna get hurt if not outright killed. If you're against humanists and spartans, be careful with guys carrying RPGs.
