The Skink is a Canadian self-propelled anti-aircraft vehicle developed on the chassis of the Grizzly medium tank, a licensed version of the M4 Sherman. The vehicle is equipped with an enclosed custom-designed fully rotating turret, providing effective crew protection and the ability to fire in all directions.

Its primary armament consists of four 20 mm Polsten automatic cannons with a combined ammunition load of 1,920 rounds, as well as a 7.62 mm M1919A4 machine gun with 2,000 rounds. This configuration provides a high volume of fire and excellent reliability thanks to the use of relatively simple and efficient weapon systems. In combat, the Skink is effective against low-flying aircraft and ground targets, efficiently suppressing infantry and penetrating lightly armored vehicles at close range.
