So, my brother has been wearing his ACH (Advanced Combat Helmet) on base for a couple weeks now. I asked him how he gets away with it, because DOD requires long sleeves and pants, reflective equipment, and helmet to ride on base. He tells me that the ACH has been DOT approved for motorcycle use. I tried looking it up, but I can find nothing on the ACH being DOT approved, and it obviously has no DOT stamp on it. Not to mention that you would plain silly wearing that thing. Anybody else heard anything on this?
