Allies:
-82nd airborne
-101st airborne
-1st airborne
I think the airborne troops only had jeeps, and light towed guns
-British XXX Corps was supposed to penetrate from the allied lines through Belgium to Arnhem. As far as I know they only had Shermans but ran out of gas about 10 miles short. By the time they got refueled, the Germans had regrouped.
German Vehicles at Arnhem:
-Jagdbapnzer IV
-Panther
-StuG III
-Pz IV
-Pz III
-Tiger I
-Tiger II
-Some captured French tanks
-a lot of half tracks, and wheeled vehicles
-A few Jagdtigers
The SS units at Arnhem were in the middle of restructuring. From what I understand, mixed units were literally thrown into action as they arrived in order to put out the allied firefights that were popping up everywhere.
