 Despite the number of registered men, the rate at which they actually volunteer for the military has fallen even further, according to the Defense Department, as less than 1% of American adults serve in active duty combat roles. Women have been allowed to serve in every part of the military, including combat roles, since 2016. That change essentially made moot a 1981 Supreme Court decision that found that banning women from forced service was okay, as the draft was meant to help the military fill combat roles, something women would not be able to do for another 35 years at that point.
