The Military Selective Service Act discriminates against men, by imposing obligations, burdens and penalties that only men face. The law discriminates against women by treating them as less than full citizens, conveying that women are less willing and able to defend the country, and perpetuating paternalistic stereotypes that, as Justice William Brennan once put it, “put women, not on a pedestal, but in a cage.” The law also undermines military preparedness. Opponents of selective service equality argue that men are on average bigger, stronger and faster than women and therefore more able to fill combat roles. But nearly 80% of military positions are noncombat roles: intelligence and communication specialists, data scientists, linguists, logisticians, network engineers, medical personnel, cloud security specialists, drone or cyber operators, and satellite communications engineers. As retired Gens. Michael Hayden and Stanley McChrystal have written, to deprive our military of half the talent and ability of the population during a potential national emergency is folly.
