The Great Khan has mainly laborers in his army that conquered and occupied 2/3rds of Europe for 300 years. He didn't treat them as soldiers and let them live in home effing with Russian and German women. Today the Pentagon militants have:
CG almost 0% combatants
AF NV <1% combatants
AR 15% combatants
MC 87% combatants
So, yeah you don't need to be fit to be a militant for the Pentagon, the NYFD, nor NYPD. But then don't pay the non-combatants the same rate, don't give them free retirement, free VA benes either. They don't deserve it if they are just doing menial jobs that an Oil Changers guy can do.
