Wars are never fought fair and square.
In order to win, militaries try to beef up their own numbers, acquire better technology, or in some cases: totally bullsh*t the other side into thinking they are going to do something they aren't really doing.
It's called a feint. In a nutshell, a military feint is a tactic employed in order to deceive the other side. A military might feint that it's going to attack Town A so the enemy shifts all its forces there, only to later attack Town B.
Here are four times the U.S. military pulled it off to great effect:
1. Both sides made fake guns out of painted logs in the Civil War.
Since photography wasn't as widespread and there weren't any reconnaissance planes, feints were arguably easier to pull off during the Civil War. That was definitely the case for the both sides, which sometimes used fake guns to trick each other into thinking they were going to attack somewhere else, or the place they were defending was heavily-fortified.
Known as "Quaker Guns," soldiers would take wooden logs, paint them black, and then prop them up on a fence or in a mount, making them look like artillery pieces from a distance. From the official US Army magazine:
When Confederate forces advanced on Munson's Hill after the first Battle of Manassas, they held the hill for three months, but when Federal troops gained the hill in October of 1861, they discovered they had been tricked. There was nothing on the hill except Quaker guns.
Quaker Guns were used before and after the Civil War. But the tactic saw extensive use by the Confederates, to make up for their lack of actually artillery.
2. The Allies misled the Germans so well in World War II, Nazi leaders thought the real D-Day invasion was a feint.
In what is perhaps the best feint ever, Allied forces during World War II confused the Nazis so well that they didn't even know what was happening when the real D-Day landings began.
The deceit goes back to a plan developed prior to the June 6, 1944 landings called Operation Fortitude. Split into two parts — North and South — Fortitude had the goal of convincing the Nazis that the Allies wanted to invade occupied Norway, and Pas de Calais in France. They really wanted to invade Normandy, but the Germans had no clue.
The Allies literally created a fake army consisting of inflatable tanks and trucks, and broadcast hours-long transmissions about troop movements that the Germans would intercept.
When the landings finally came at Normandy, German commanders thought it was a smaller force, and the much larger attack was happening later.
"North of Seine quiet so far. No landings from sea. Pas de Calais sector: nothing to report," a German message on June 6 reads. Then about a day after invasion, forces were warned: "Further enemy landings are to be expected in the entire coastal area. Enemy landings for a thrust toward Belgium to be expected."
The Allies were pretty awesome at this deception game. Just one year prior, they fooled the Germans using a uniformed corpse with "top secret" documents into preparing for an invasion in the wrong place, when the Allies instead invaded Sicily.
3. The US Army built a fake base to fool Saddam Hussein, and it worked.
The ground war of the Persian Gulf War was over pretty quickly, thanks to Gen. Schwarzkopf's extensive planning and leadership. Schwarzkopf wanted to use a "left hook" or "Hail Mary" play of his forces, effectively cutting off Iraqi forces in Kuwait by going behind their lines.
But in order to achieve it, Schwarzkopf needed to trick the Iraqi Army. Instead of Iraq thinking they would get hit with a "left hook," Army planners wanted them to think the U.S. would invade near Kuwait's "boot heel." FOB Weasel was how they did it.
It was eerily similar to Operation Fortitude. From a previous article by our own Blake Stilwell:
FOB Weasel was what Rick Atkinson, author of Crusade: The Untold Story of the Persian Gulf War called "a Potemkin base… giving the impression of 130,000 troops across a hundred square kilometers." Army truck drivers wearing the red berets of paratroopers would shuttle vehicles between FOB Weasel and logistic bases.
The U.S. army's XVIII Airborne Corps established FOB Weasel near the phony invasion area. They set up a network of small, fake camps with a few dozen soldiers using radios operated by computers to create radio traffic, fake messages between fake headquarters, as well as smoke generators and loudspeakers blasting fake Humvee, tank, and truck noises to simulate movement. Inflatable tanks with PVC turrets and helicopters with fiberglass rotors were lined up on the ground as well. Inflatable fuel bladders, Camo netting, and heat strips to fool infrared cameras completed the illusion. The Americans even taped "Egyptian" radio traffic messages about the supposed American presence to be intercepted by the Iraqis.
As Stilwell notes, even well after the Iraqi Army was expelled from Kuwait on Feb. 21 1991, Iraqi intelligence still thought American forces were near the "boot heel."
4. The insurgents knew US troops were coming before the Second Battle of Fallujah, but they had no idea of when or where.
Before the Second Battle of Fallujah in 2004, insurgents were well aware that an attack was on the horizon. The city had become completely lawless, swept up by a large number of insurgents, who were spending their time building up defenses in the city.
On the outskirts, Fallujah was completely cut off by U.S. troops surrounding it. Insurgents inside the city knew they would eventually be attacked, but a series of feint attacks made it hard to pinpoint from where or when. And beyond deceit, the feints allowed troops to test out enemy capabilities before the main effort.
From the Marine Corps Gazette:
Marine battalions manning vehicle checkpoints (VCPs) or participating in feints were extremely successful in targeting fixed enemy defenses and degrading insurgent command and control capabilities. A series of feints conducted by 1st Marine Division (1st MarDiv) deceived the insurgents as to the time and location of our main attack. They knew we were coming, but they didn't know when or from where. The feints also allowed us to develop actionable intelligence on their positions for targeting in Phase II. The Commanding Officer, 3d Battalion, 1st Marines, whose Marines manned the southern VCPs around Fallujah, described this period as a real-world fire support coordination exercise that provided a valuable opportunity for his fire support coordinator and company fire support teams to work tactics, techniques, and procedures and to practice coordinating surface and air-delivered fires.
In an interesting example from a grunt on the ground, a feint attack from Lima Co. 3rd Battalion, 1st Marines tested enemy defenses and helped planners realize the spot they feint attacked wasn't the best for the real thing.
"Had we decided to attack from the south, the battle would have been hellacious from day one," one Marine recalls in the book "We Were One." "The thing we discovered after the battle was they oriented a lot of their defenses to the south."
