Medical technicians walk around to assist visitors during the Joint Service Open House at Joint Base Andrews May 18. The medics provided everything from basic chapstick to ear plugs. This year's Joint Service Open House celebrates the Centennial of Marine Corps Aviation. JSOH affords the public an opportunity to meet the men and women of the Armed Forces while viewing over 100 static displays and 19 aerial demonstration teams.
