OK, tried to do a better job with bitmaps this time. Unfortunately, I am not good at it. But this is a start right.
Ambulance Truck:
Medical Squad / Medical Platoon:
Stefan,
Attached are the bitmaps and bittypes for the said units (Dressing Station, Main Dressing Station, Ambulance, Medical Sqd/Pltn). The bittypes are probably out of whack as I can't test them before the files are encrypted.
If you could proceed in creating the platoonXX.oob values for these guys, I could in turn ask Jason to encrypt them for the EF:FB. Then I could test them as well.
I just noticed the Red Cross is on a square white background on ambulances, I will continue on the bitmaps more later on to improve them further. This is again a quick hack having had like an hour to work with them.
