Kz 8 cm GrW 42

The kurzer 8 cm Granatwerfer 42 (kz 8 cm GrW 42) was a mortar used by Germany during World War II. It was developed as a lightened version of the standard German 8 cm GrW 34 medium mortar with a shorter barrel for use by paratroopers, but replaced the ineffective 5 cm leGrW 36 as that weapon's shortcomings became apparent. The kz 8 cm GrW 42 fired a bomb over 3 and a half times heavier twice as far as the smaller mortar, but was less than twice as heavy. It broke down into the standard three loads for transport.
