From the uniform in the photos definitely not Luftwaffe, and not SS. He was in Heer.
If he was in Rzhev area in June 1942 it might help to guess which division he was in. The documents that you posted in another thread said that he was from Darkehmen/Angerapp area in East Prussia. Darkehmen was renamed Angerapp in 1939. I believe it was close to Insterburg
Most divisions in Heer had a 'home' military district (Wehrkreis). Each Wehrkreis had a number. Wehrkreis I was East Prussia.
Here are links to maps of Rzhev area battles.
Russian map dated January 4-11, 1942: http://www.rkkaww2.armchairgeneral.com/ ... _11_42.jpg
German divisions listed on it:
339 ID (Infantry Division, marked on the map in Russian as 'nd'. Note that Russian infantry divisions are marked with letters 'cd')
216 ID, 110 ID, 6 ID, 26 ID, 86 ID, 206 ID, 161 ID, 46 ID and 256 ID.
Out of these divisions 206 ID and 161 ID were raised in Wehrkreis I, i.e. in East Prussia.
26 ID was raised mostly in Wehrkreis VI (Rhineland-Westphalia) but it also had some East Prussians.
I don't have a battle map for May-June 1942 but here are Russian and German maps dated late July-August 1942:

They list 253 ID, 206 ID, 251 ID, 87 ID, 256 ID, 14 MD (Motorized Division), 72 ID, 161 ID, 129 ID, 102 ID, 5 PzD (Panzer Division), 36 MD, 1 PzD, 2 PzD, 342 ID, 78 ID. Out of these divisions, 206 ID and 161 ID were from East Prussia. No 26 ID at this time.
Here is a German site with information on Wehrmacht units. My German is minimal but I've been able to read it with Google Translate.
161 ID http://www.lexikon-der-wehrmacht.de/Gli ... /161ID.htm
206 ID http://www.lexikon-der-wehrmacht.de/Gli ... /206ID.htm
26 ID http://www.lexikon-der-wehrmacht.de/Gli ... n/26ID.htm
Each of the pages has the division symbol at the top. You might want to look for it, as well the division/regiment numbers in your photos. For example, vehicles were often marked with a division symbol, and signs on bunkers could denote the army unit

If you click on it, it will show an enlarged picture of the area you clicked on. Another click, and it will give you an even more detailed area map. Gross Medien is south of Angerapp on it.
Hope this helps a bit.
