WASHINGTON (AP) — By asking to be known as a woman named Chelsea, Bradley Manning has created a host of possible challenges for the military as the soldier begins serving a 35-year prison sentence for giving secrets to WikiLeaks.

Manning's gender-identity struggle — a sense of being a woman in a man's body — was brought up by the defense at the court-martial, and a photo of the soldier in a blond wig and lipstick was submitted as evidence.

But the latest twist, announced Thursday, surprised many and confronted the Pentagon with questions about where and how the Army private is to be imprisoned.

The former Army intelligence analyst disclosed the decision in a statement provided to NBC's "Today" show.
