You aren't using them to raze effectively then. They are easily profitable if used for that and killing really vulnerable stuff they can get at (when they do they steal gold and research and of course get XP that can expand their fighting capabilities to really terrifying levels if you're careful with them enough until they reach that point.)And one more opinion. I consider crime units useless. Their only use for me is bringing EP from infiltration. Their upkeep is too high. They cannot capture units.
Strike Teams can capture units (like Workers) and are much more efficient in stealth combat.
I think the only problem here is that DH has never realized they are black operatives of the state.
