US permanent resident traveling to london
i am a permanent US resident and an active duty member of the army branch permanently stationed in germany. i am trying to find out if i will be stopped at the airport if i go there with my Military ID, leave form(government travel order) and my german ID. i dont have any passport at all. do not know what happen to them. i ask our travel agency on base and they said i dont require a passport but i want confirm because all these website i have been visiting are telling me otherwise.
