As far back as documented history goes, war has crushed civilizations and built new empires. Regardless of era, military leaders and warlords have long sent visual (or "FU") messages to their enemies in hopes that emotions, not tactics, take over the battlefield.
With both sides desperate for a victory, the art of mind manipulation can trigger a response that just might reduce the enemy's will to fight.
1. Tossed in a gutter
ISIS controls many areas in Iraq, but that doesn't stop members of the Iraqi forces from showing their own progress.
According to Fox News, Iraqis toss the dead bodies of ISIS members in the street gutters as a form of intimidation to ISIS sleeper cells and their supporters.
2. Drawn and Quartered
Most of us are familiar with William Wallace's legacy, especially if you've seen Mel Gibson's Braveheart. What the award-winning filmmaker didn't show was what King Edward did after the end credits rolled.
According to duhaime.org, the King of England ordered his soldiers to cut Wallace's body into four pieces and post them at the four corners of Britain. Wallace's head was stabbed with a spike and set on London Bridge for an epic "screw you" message.

3. Capture the flag
Those who have had the opportunity to fight in a Taliban-infected area probably noticed the white flags flapping in the wind over extremist strongholds.
Marines love flags, too — especially their own, which wave high above American positions. They also enjoy taking the Taliban flags and putting them on display for the bad guys to see.

4. A good slicing
Around 500 B.C., a war between the State of Yue and the State of Wu in China broke out.
Gou Jian, the King of Yue, was unsure of his victory over the Wu. To try to gain an element of surprise, Jian ordered 300 of his men to stand in front of the enemy, remove their swords and cut their own throats before the battle began.
The Wu were so completely stunned, Jian was able to send in his attack on the unsuspecting army and defeat them.
(We actually don't recommend this tactic...)
