7 craziest ways you could fight in the World Wars

The two World Wars were some of the first true industrial wars, forcing leaders to innovate so they would lose fewer troops and have a chance at victory. While some were slow to change, some leaders figured out truly novel ways of using everything from bicycles to railroads to artists. Here are just seven of the crazy jobs that were created:

German bicycle troops in World War I.

Bicycle troops

Believe it or not, bicycles were a huge part of World War I. France and Britain has about 250,000 troops in bicycle units by the end of the war, and most major combatants had at least a couple thousand. This included bicycle couriers, reconnaissance cyclists, and bicycle infantry, all of which were exactly what they sounded like.

But there were also more surprising applications. Some bicycles were welded into tandem, side-by-side configurations that allowed cyclists to create silent, mobile machine gun platforms, ambulances, and even vehicles with which to tow small artillery.

Want to work on two wheels but don't want to pedal so much? Fair enough, maybe the motorcycle corps was for you. Motorcycles were used for everything that bicycles were, and occasionally even pressed into service as anti-tank weapons. But the craziest way to use motorcycles was definitely tank recovery.

See, before a random tank operator thought to convert some tanks into recovery vehicles, the Army used motorcyclists to deliver tools and spare parts to tanks under fire on the battlefield. While this was fast, it meant that a motorcycle rider had to tear through No Man's Land under fire that had just crippled or bogged down a tank.

Fake Army/city creator

On both sides of World War II, artists were put to work creating decoy forces or, in the case of Britain, decoy cities to draw away attackers and waste the enemy's resources. The most famous of this is likely America's "Ghost Army," a collection of mostly inflatable military hardware complete with fake radio traffic that caused the Germans to overestimate the enemy they were facing and even got them to think D-Day was a feint.

But perhaps the most ambitious program was in England where engineers created entire fake cities and landing strips, complete with lights, ammo and fuel dumps, and planes. They were able to convince German bomber crews at night that they had reached their targets, resulting in thousands of tons of bombs dropping on fake targets.

Guerrilla warfare fighter/trainer

For major combatants with lots of territory to fight over, it's always easier if you can put a small number of troops or trainers into position and force a much larger enemy force to remain there to fight them. That's what America achieved with guerrilla trainers like Detachment 101 and the British achieved with guerrilla units like the Chindits.

In both cases, sending in a couple dozen or a couple thousand men tied down entire Japanese divisions and inflicted heavy losses. The situation was similar in Europe. A Marine guerrilla warfare unit of just six men provided support to French resistance fighters and killed so many Nazis that the Germans assumed they were an entire battalion. And they achieved this despite losing two Marines on the jump into France.

Bagpiper/swordsman/bowman

Granted, these jobs only came up under one commander: Jack "Mad Jack" Churchill, a British officer who led his men onto the beaches of Normandy while carrying a claybeg (basically a smaller claymore) and a longbow. And he did use the weapons in combat, at one point riding through France on a bicycle with his quiver hanging from the frame.

And, on D-Day, British soldier Bill Millin, a personal piper to Lord Movat, was ordered to play his bagpipes as his unit hit the sands of Normandy. The Millin wasn't shot and asked a group of Nazi prisoners of war why no one hit him since he was such an obvious target. The German commander said "We thought you were a 'Dummkopf,' or off your head. Why waste bullets on a Dummkopf?"

Chemical warfare operator

The first large-scale deployment of chemical weapons came at Ypres, Belgium, in 1915, but, luckily, was largely outdated by changes in international law before World War II, so there were just a couple of years in history where offensive chemical warfare operators were a real thing.

That first attack required hundreds of German soldiers to bury 6,000 steel cylinders over a period of weeks, but allowed them to break French lines across an almost 4-mile front. But it was hard to exploit gaps from chemical attacks since, you know, the affected areas were filled with poison.

Railway gun operator

If you've never seen one of the railway guns from World War I and II, then just take a look at the picture. These weapons were massive with 14-inch or larger caliber guns mounted on railway carriages. When the U.S. joined the war, they immediately sent five naval railway guns across the Atlantic.

Railway artillerymen were usually outside of the range of enemy fire, so it was relatively safe. But expect some serious hearing loss and even brain damage. Massive amounts of propellant were required to launch these huge shells.
