Hi Thank you for these pics
We can see: an UAZ- 469 Light vehicle, an IFA W-50 ( a truck widely used by iraqis, built in the former east germany during the 70's and 80's), a ZPU-4 anti-aircraft gun
The artillery piece seems to be a 122mm D-30 with a missing trail leg (I don't know the english word for this).
Very interesting pics
Cheers
JJ
