Military close combat with a helmet..
Hm: "Improvise, Adapt and Overcome!"
I know how to use a lot of different military gear for close combat, but I don't think I have tried the helmet as an offensive weapon..
But if you have nothing else you must improvise.. 8)
Actually, I have a very old Navy SEAL training manual that advocates using a sentry's own helmet for that purpose.
