Same with the UK troops, one of the teachers (Sarah) where my wife works has twin brothers, just the other year one was in Iraq, and one in Afganistan - I'm not sure if they still are or not?.
Sarah got married the other year, in Las Vegas - which she would recommend highly. Her brothers were allowed in the casino for the ceremony, but had to leave afterwards as they weren't 21 - they also weren't allowed to drink alcohol in Las Vegas. So they put their uniforms on, along with their campaign medals - and found the ladies of Las Vegas very keen on UK uniforms
