Gay and in uniform

It's now more than 20 years since the ban on gay people serving in the armed forces was lifted. But what was it like for gay and lesbian people serving before that? We hear about the lives of gay men in the two great wars, how the army was an escape from society's heterosexual norms for lesbians and what museums are doing today to make their collections more representative of everyone who has served their country - gay or straight. And a gay soldier tells us how joining the army gave him the strength to finally become his real self.
