Soviet abbreviations for Army Rear Area Units

[Der Alte Fritz]

Am trying to translate a table relating to the relocation of 8th Army Rear Units and am stuck with some abbreviations:

Пол. арм. продскл. = Regiment. Army. Food/Fodder Warehouse?

УПЭП = some sort of hospital evacuation point

УГПЭП

ПОРСАМ = Mobile Repair ???????? Average Repair

АРАМ = Army Repair Shop??

[Art]

Пол. арм. продскл. = Regiment. Army. Food/Fodder Warehouse?

Пол. is for полевой not полковой. So "field army food depot"

УПЭП

HQ of field evacuation point

УГПЭП

HQ of forward field evacuation point. Both are basically medical headquarters controlling hospitals in the army area

АРАМ = Army Repair Shop??

Army artillery (ordnance) workshop, I guess

ПОРСАМ = Mobile Repair ???????? Average Repair

don't remember. Must be some workshop for clothes or footwear or something like that.

ПОРСАМ = Mobile Workshop for Repair of Saddlery and Harness

found ШОРСАМ in the Glossary!

Thanks for the other explanations, some of these are very rare.
