I have a friend who was in the US Army and was not religous at the time
He was in Southern France and the local Chabad Rabbi went on the base and asked the Officer if there were any jews on the base.
My Friend figured it was a great way to get better food than the army and went for Shabbos at the Chabad Rabbi. That small step made him more appreciate of the religous and became frum himself and married a frum woman and they have all their kids in Yeshiva
