My issue is would a gay Marine who fell in love with another gay Marine be willing to make the ultimate sacrifice for their lover or maybe order their partner take the bullet. Would emotions get in the way at the critical moment? Cloud their judgment, cause bad decision making, not be able to accept the loss of their partner and continue the mission. And then there are issues of senior/junior partners and favoritism problems. Tough enough with co-ed units so adding gays to the mix adds more to the combat stress.
