Disarmed and dejected Japanese soldiers seen after the surrender of Japan.

It's over

The Type 89 Knee Mortar was issued at the platoon level to a single soldier who carried the tube strapped along the leg. This led quickly to the weapon being referred to as the ‘leg mortar.’ When US troops captured these weapons, a bad translation of this moniker led to the term ‘knee mortar’ and it has stuck. The curved T-shaped base of the Type 89 seemed to reinforce this belief. However, when US troops tried to test fire recycled knee mortars from the knee, broken bones happened.

Type 89 Knee Mortar

The Japanese painted a decoy B-29 with a 300-foot wingspread, so scaled that it appears to be flying at several thousand feet, on the Tien Ho airfield in China on March 9, 1945. From a great altitude the decoy gives the illusion of a B-29 in flight with flames streaming from its port inboard engine. The Japanese figured other planes would drop down to investigate and become targets for heavy concentration of flak.
