Canon de 25mm Antiaérien "Hotchkiss"

The Canon de 25mm Antiaérien "Hotchkiss", or the 25mm Hotchkiss, is a French anti-air autocannon designed and produced before WW2. It armed France's anti-air units on the eve of the invasion of Alsace-Lorraine, bringing terror to German dive bomber units and infantry alike. After the French defeat, the Germans retrofit these cannons into a number of armoured vehicles and ships, and later sold them off.
