It sure looks impressive ! Congrats for your setup .
If I may, a few suggestions :
Try and avoid overloading the lot - keep medical related and non-medical items separate - limit the number of very young re-enactors (btw, the use of civilian youngsters is an excellent idea) - respect WW2 clothing and hairdress of military re-enactors - field medics were usually not overburdened with military gear, they gave priority to medical items - German medical personnel should not wear ammo pouches - medical personnel operating at Aid Stations and Hospitals should only wear their 'specific' medical items - when treating casualties, remove web, gear, gloves, and anything that might impede the patient's movements .
Hope this helps ...
