Effective mobile defence against low-flying enemy fighter bombers was a key development in WWII. It required a vehicle that could keep up with the armoured columns it was to defend, as well as one tough enough to mount viable weaponry. In the M16, aka the “meat chopper” the US and Allied forces had such a piece of kit! Check out the old Matchbox 1/76 M16 halftrack, the first completed piece of armour on the Ships and Tanks page!
