Summary

Exclusive photographs reveal heavy machine guns mounted aboard the Russian gas tanker Proms Marshal Vasilevsky supplying liquefied natural gas to the Russian exclave of Kaliningrad. The tanker sailed past Latvia, Estonia, and Finland in the Baltic Sea with sandbagged firing positions and lethal court heavy machine guns on its bridge. This is the first documented case of such weapons on Russian civilian ships. The ship's manifest showed 50 passengers alongside crew since August of the previous year, many with past service in Russian military and intelligence, including FSB, and former Wagner mercenaries. Experts interpret this armament as an aggressive signal to NATO to prevent boarding attempts, despite the risk of a deadly explosion due to ammunition being carried alongside flammable cargo. Private military contractors aboard have orders to open fire against attempts to seize the vessel by third parties, intending to physically eliminate attacking Western military personnel.

Classification

Confidence: High

The physical armament of a civilian gas tanker with heavy machine guns, presence of private military contractors and former Wagner mercenaries, and explicit intent to deter or respond violently to NATO boarding attempts indicates a clear hostile militarization and hybrid warfare tactic.
