In 2010 the Russian tanker Moscow University was captured by pirates off the coast of Somalia. The Russia anit-submarine ship Marshal Shaposhnikov was nearby and quickly recaptured the tanker. The Somali pirates were carry the usual gear, rusted AK rifles (with no stocks) and RPGs.
Apparently the guns were in working order and well oiled inside.
After the ship was captured the pirates were patched up by medics, given food and water and then released.
