Necessity is the mother of invention and it appears the Ukrainians are doing a good job of it. They have captured a number of abandoned or semi-destroyed Russian Army tanks and armored personnel carriers. Who has not seen the videos of Ukrainian farmers towing away Russian tanks with their John Deere tractors?
Most of these vehicles are armed, in part, with the Russian PK-T machine gun. That is the tank or coaxial version of their standard PK machine gun. France 24, the French public TV network, has a story on how Ukrainian auto mechanics are re-engineering and repurposing these tank machine guns into infantry weapons. They have added a stock and bipod as well as converted the firing mechanism. You can it in the video below.
Repurposing tank machine guns for infantry use is nothing new. As Ian McCollum relates in the next video, the Finns did it extensively with captured Soviet weapons in the Winter War.
