Hello yan2309...
RD-47 has been mentioned here,
please, follow the link:
http://forum.valka.cz/viewtopic.php/t/34888
then scroll down and find a picture catching two Czechoslovak paras unpacking tarasnice bazooka from a parachute container.
These two guys are carrying RD-47 backpack in "run away" or "carry all the day long" position.
There must be another picture in the same topic catching the way RD-47 harness was made a bit softer by adding extra pads...
When speaking about picture shown in your last post I have to say I would expect Egyptian paras using materiel of Soviet origin but who can say...
Hope this helps a bit..
