Russians poke fun at U.S. M113; Armored Personnel Carrier stuck in Ukraine mud

The M113 was the first aluminum-armoured vehicle to be put into large-scale production. After the appearance of the M113, several other armoured carriers, light tanks, and self-propelled guns were built with aluminum armour. Within 30 years, the United States had produced more than 76,000 M113 APCs and their derivatives, making them the most numerous armoured vehicles outside the Soviet bloc.
