Osprey.Man At Arms No. 229. Luftwaffe Field Divisions 1941-45.
I think that you find it very helpfull.
For the squad organisation the 10 man squad is o.k, just avoid the use of a second machine gun as only the panzer grenadiers and the SS used them at least up to 1943.
At the end of that year the Army took over and the indipendency of the Luftwaffe divisions practically ''died''.
Also don't forget that Luftwaffe units didn't get always first class equipment, MG 15-an aircraft machine gun converted for infantry use instead of MG 34, Pak 97/38-a French 7.5cm model 1897 gun modified with the carriage of the German 5cm Pak 38 and so on.
In a 10 man squad give to your squad leader an MP 40 and if you are using them in the eastern front give a captured PPsH 40/41 to your second in command, for the squad suport an MG 34 is enough and the rest rifles.
For your 4-5 man Command squad, give your officer only his pistol, your n.c.o with an MP 38/40, and your officer aid as the two runners will be armed with rifles.
Scoped rifles, grenade launchers, radios and other ... ''exotic'' equipment, well at least for the Luftwaffe men, forget them !
But don't forget that you are playing a game and if you want you can use anything as long as you come up with a story :
'' Look Helmut what i found in the battlefield, a scoped Kar98 ! ''
Hope that i helped._
