107mm rocket - Type 63 launcher. Extremely common. Not US manufacture.
Search for '107mm rocket', Anon. They are everywhere. Israel seized some in 2009 with same/similar English markings.
Does America use or manufacture 107mm rockets, Anon? C'mon man!
They are tiny short-range rockets, Anon. Chinese multi-tube Type 63 launchers. They are ubiquitous in the Middle East.
They are made everywhere. They are in the field everywhere. They are cheap and rather crude. Poor man's Katyusha but not nearly as effective.
