I was watching a Youtube clip of WW II attempts to destroy Japanese pillboxes/bunkers of that era. These were constructed at Aberedeen Proving Ground ca. 1943 or so. One weapon which did prove effective against them was the 4.5" tube launched folding fin rocket. These were carried at times by P-47s and P-38s in clusters of three. They were also mounted on M-4 Sherman tanks, and fired from racks mounted on LCIs in the Pacific. The launcher snown was an open tube, maybe five feet long, and with bipods at both ends. The rocket was fired by electric impulse through about ten feet of wires and either a battery pack or magneto device. I have never seen some of the waepons shown in that film. One being a 37mm gun mounted on a .50 M2 tripod.
