by the Office of Strategic Services, Simple Sabotage Field Manual (August 2019)
“ Acts of simple sabotage are occurring throughout Europe. An effort should be made to add to their efficiency, lessen their detectability, and increase their number. Acts of simple sabotage, multiplied by thousands of citizen-saboteurs, can be an effective weapon against the enemy. Slashing tires, draining fuel tanks, starting fires, starting arguments, acting stupidly, short-circuiting electric systems, abrading machine parts will waste materials, man-power, and time. Occurring on a wide scale, simple sabotage will be a constant and tangible drag on the war effort of the enemy. ”
