I was thinking that until I finish preparing the historical articles I was planning, this kind of articles would serve well enough. Please tell us in the comments if you like them or not.
122 mm D-30 Howitzer mounted on a M113 chassis in Libya (there’s still a civil war there since 2014). The D-30 is of Soviet origin, produced since the early 60’s to this day. Judging from the photo, at least 3 were modified in this manner. Previously, only 120 mm mortars, various AT systems and AA weapons were seen mounted on the light 10-ton M113.
