Um pretty sure that the Miniman should be the PAR67, the PAR70 is the M72A2. They are so similar in appearence that it is confusing, also, during basic sometimes recruits shot the par67 as we are (have) gotten rid of them.
The Par67 goes to the reserve units around 1980 and should be out of general use by 1994, although the joke is that 20 year old (stored) PAR67 is safer to fire then a 15 year old PAR70.
Puch G or Pinz 4 (with M2) were used in KoPoSiPo function, but uparmouring is a bit dicy, you're right. Maybe just give it a 1 frontal armour (for the shield)? pls?

The Jäger company did not have engineers, but the BN often did - thanks for pointing that out. It is the 4th platoon of the S-Kompanie (KU-K), just 3 engineer groups (Satchel and Claymore) with the standard command section, as listed.
The Gaurd Support company (for the BN) prolly has a engineer platoon as well, but we did not cover that anyway. The HONOUR GAURD company, which these days rotates (used to be 4.Co.) had an enginner group/detachment/platoon (around 20-30 guys IIRC) that had a very strange job indeed...
On vision, again good point, from say 1985 ALL ACTIVE (not landwehr, we will get there) squads had 1, sometimes more, Starlight Scopes (vision 10?15?20? no idea). The snipers in the active units all had them, however on the "normal" sniper rifles SSG-69. The "heavy" snipers in the honour gaurd might have had the SSG-69 or somethign else (i am going with something else) but definetly had full NVGs, as did all HOUNOUR GAURD platoons
