On Military Appreciation Day, active Reservists, Guard, Active Duty personnel and veterans from all branches and conflicts converge on the MPAC along with military vehicle enthusiasts who line the driveway with Jeeps.  A  "Fall In: All in" all service formation is called for a 15 minute ceremony which includes the National Anthem, Moment of Silence, Prayer, and "Last Hoorah/Hooah" in which the oldest living veteran is identified, brought to the head of the formation and awarded a US lapel pin.  The ceremony concludes with all present joining in "God Bless America."  The remainder of the time is spent in camaraderie, taking in the MPAC collection, the military Vehicle collection and a barbecue.
