The submarine I-15 taken sometime before November 2, 1942 carrying two Ka-Tsu's. The standard armanent of the Ka-Tsu was two torpedoes or two 25mm. However the one on the right appears to have torpedoes and 25mm guns, possibly fitted by removing the superstructure that appears on the left vehicle.----Winston
