Other divisions that participated in the Italian campaign include the 34th, 36th and 45th Infantry Divisions along with the 82nd Airborne Division (or elements thereof). All were under 5th Army in either II or VI Corps. Smaller units included the 509th Parachute Infantry Battalion and the FIRST SPECIAL SERVICE FORCE (Black Devils). The FSSF is near and dear to my heart, as I command the FSSF Living History Group.
As to what medics carried, it was really personal preference. There was a specific setup for medics which included a yoke and two bags which rode high on the medic's hips. He could wear a haversack over the yoke, but more likely would have a musette bag, as they could carry more and were less awkward. One interesting thing I've seen with medics was the use of ammunition bandoleers to carry Carlisle Bandages.
