Three men in the back are the crew of the armored ambulance. Six men on the left are the combat mediks. Two man with white officer hats and epaulets are surgeons/physicians and the man in white coat is the high level bureaucrat from the army medical command.
On the battlefield some people are more important than others. Armored ambulance is for the emergency situations when an important person is injured on battlefield. The ambulance could be count as a mobile "Sickbay" from the Brikwars 2001 rules.
Back-hatch can be oppened to load strecher.
Combat medics have custom stickers on front and back of the torsos and equipped with med-kits (black suitcase pieces)
Surgeon is equipped with med-kit. Surgeons are basically mediks with higher skill rating.
Bureaucrat from the army medical command is a special character (I thought maybe this type of unit can give bonus +1 skill to all medics and surgeons for their medical actions)
