1. Heil, Mickey Mouse
This German audio-visual apparatus was designed to enhance the boom and flash of enemy artillery and, thus, help pinpoint gun positions.
2. Not So Shining Armour
Unwieldy and cumbersome, but the Brewster Body Shield could still stop a machine gun bullet.
3. Man Over-Bed
US sailors were trained to strap on bed mattresses in the absence of lifejackets.
4. Pedal Power
German soldiers generating electricity for communications and light.
5. Now Hear This
Recruits at a US Navy training camp in Seattle receive an earful.
6. Homemade Tree Stump
Both sides would remove shell-damaged trees under cover of darkness and plant fakes – like this one installed at Souchez in May 1918 – to house snipers and lookouts. Made of canvas and chicken wire, it tested the nerve of the bravest occupant.
7. Dummy Tank
Australian engineers from 4th Field Company maneuver a dummy tank, made of wood and canvas, ahead of an assault on the Hindenberg Line in 1918.
8. Bird’s Eye View
A German spy pigeon wearing a time-delay camera on an aluminum breast harness.
9. Bush Fire
Camouflage became increasingly elaborate as the war progressed. Here, Allied trips show off a captured Turkish sniper near Gallipoli in 1915.
10. Hide And Seek
This 1917 US experimental camouflage suit has not deemed a success. The wearer might as well have been carrying a sign on his head.
11. In The Saddle – 1915

13. Cutout Soldiers
The British Army Camouflage School in Kensington, where cutout soldiers were designed to mislead the enemy during attacks.
14. Paper Mâché Heads
First made by the French in the winter of 1915, were used to flush out German snipers.
British homing pigeons were parachuted into occupied territory with a request for local civilians to write down local troop positions, attach it to the bird and then release it. The Germans soon rumbled the plan and replaced Tommy pigeons with their own birds which would fly back to Germany.
