Gays and Lesbians in the Military During the Second World War.

Long before the policy barring gays from serving openly in the military ended, Air Force 1st Lt. Josh Seefried started OutServe, a network of gay troops on Facebook. Seefried and his partner talk about what it's like being a gay couple in the military — and about new challenges facing gay troops.

A study of five U.S. allies who ended bans on gays openly serving in their militaries showed that the wide-scale disruptions feared by opponents had never materialized, says historian and study author Nathaniel Frank. He discusses his finding and what they suggest for efforts to end the Pentagon's "don't ask, don't tell" policy.

Seven years after being discharged from the U.S. Army under "Don't Ask, Don't Tell," openly gay veteran Alex Nicholson is the executive director of Servicemembers United, an advocacy organization he founded.
