Only way they get the same size if it a 2 bedroom house that either are applying for. I, myself, can apply on either a 3 bedroom or a 4 bedroom, only cause I have 3 kids and the age difference between my boys is on the boarderline. If someone that has 2 kids, and they are the same sex and close in age, then they could share a room and could apply for 2 bedroom. That is the thing I was talking about.
Now, with the gay couples, how did they have kids? adopt? Got pregnant? If they got pregnant, then how that happened? The military can take someone to court if they have an affair outside the couple relationship (3some, mistress, prostitute).
If you look into some the rules and laws that a military person has to live by, gays and lesbians could get in trouble with just being the way they are. The missionary is the only sex position allowed in the military, and sodomy not allowed too. Now, it unusual to see someone charged for those, but the adultery is likely, and then they can add those other charges.
Now, if they adopted the kids, then they had to go through a court system, which would take about the same amount of time to upgrade in the housing list.
