An annoying trap.

On the battlefield of a simulated confrontation exercise, I saw the retreating Red Army planting cartoon boards on the roadside to vilify the enemy. Next to the fortifications, there was a big slogan cursing the Blue Army. On another highland, there was a kneeling blue army officer who threw leaflets to disintegrate the Blue Army. The slogan of stimulating the Blue Army was endlessly played in the loudspeaker ... which made the Blue Army unbearable. It turns out that these are all clever tricks set by the Red Army. Gently remove a cartoon, and you will see the fuse connected with booby traps on the board. Follow the fuse that is not easy to find, and you will see the mines buried under the turf. After careful observation, it turned out that invisible mines were attached to slogans, grass figures, leaflets, speakers and other objects. In this way, mines are placed in hidden places with strong senses such as sight, hearing and smell of the enemy behind or near the battlefield, which constitutes an irritating booby trap. Angry booby traps have been tried and tested in battlefields all over the world. They use the shameful and impulsive behavior of the enemy to cause enemy casualties, especially the booby trap that vilifies the idols, beliefs and personalities worshipped by the enemy, which makes it easier for the enemy to be fooled.
