This event I'm working with Beltuinn's Free Company of Foote, but we are portraying ourselves as the Massachuessetts Militia circa 1636. This group does late 16th to mid 17th century and tweaks itself to the particular event they are doing, like this one. They also portray and Elizabethan Trayned Band at the Pa. Ren. Faire. Military Heritage days should be pretty cool as it will have reenactors and displays from all eras of US military History and even some current active duty Army personel.
