I chose Men and what im basically seeing here is it lets you relax somewhat and Zerg Rush missions with slave soldiers if you dont care about them dying... and because of their limited health any wounded will not have too long to recover. The crusader armor also gives them like 30ish Armor so they can take a hit or two and might shake it off just like gals do. Also remember there are Accurate weapons like the Scoped Carbine+EP rounds, Commando Rifle, and dudes are just as dangerous with Grenades as anybody else. And grenades only weigh 3-4 pounds, its not a 20-40 pound gun... imagine 10 guys loaded with Grenade Launchers/WP and Hellerium Grenades... glass hammers are still hammers.
You can make slave soldiers from Slaves too, you can make lots of them and then just ship them off to the Hot Tub base so they can steadily cook up their stats. Its definitely an Attack Dogs sorta option.
I haven't exactly been doing this because I threw a BUNCH of money into Freaks since theyre the only ones who can wear certain armor types (Ghost, im looking at You). And ive got a stock of Lokknarrs that I keep around. If I need suicide bombers with timed baby nukes im definitely enlisting the 'Soldiers though. They could at least have a chance to get it to where it needs to go, the goblin girls will just get shot down in the street.
What im not doing is investing anything into peasants. Im losing some missions I cant participate in but thats just how it is.
Edit:
One thing im really doing anymore is LIMITING the size of my deployments, like just 2-3 top notch Hands, it takes longer to finish the missions Turnwise but each Turn is shorter. Some exceptions like Mansions and pogroms possibly but im even considering a 4 Gal load with an armored car for pogroms, and I can take down a Mansion with 8 easily (since the girl on the roof can show me where the guard stacks are).
I might even take 4 gals to a Mansion just to sweep it for treasure chests and money bags (still havent found where those uranium briefcases are though).
