Scott:
Do a search on "casaulties" or "wounded" on e-bay (Toys&hobbies) and you will find a lot of wounded/dying/dead figures. Almost all of them are resin.
To my knowledge there are only two plastic kits with German casualties on the market, both are from Dragon/DML:
"German medical troops" Prod.no. 6074.
"Fallen comrade (Aachen 44)" Prod.no. 6119.
Both kits are very good.
Hope that helps.
