panzergrenadier? help!!!!!

[Cpt. Dirk Diggler]

If any one can help, ive just got my hands on a panzergrenadier platoon and a stug g platoon from flames of war
but as i'm not 100% on ww2 can anyone tell me a good route to go from here. I.e can i use the grenadiers as ss? does any one know any platoon/company names or designations. Where do i expand from here?

Anyway if you can offer any advice it would be warmly welcomed!

Thanks
