Hafzas right now are basically undercover boss the unit. CB has been into rewriting units lately so personally I'd rewrite hafza. Have them replace ghulam and aguciles in QK completely. Keep them LI and keep holomask. Give them higher grade gear than what we are used to in Haqq. Give them FT:Core. Now you have yourself a real shell game. Is that a core of Djans? Is it Janissary? You don't know. You don't know what they have either. Maybe give them an MMR and some smgs, a spitefire and breaker marksmen rifles or something.
