The photographer was accidentally injured.

Although war will cause a lot of casualties and property losses, it also promotes the rapid development of science and technology. In the process of developing all kinds of new weapons, it is inevitable that some inventions that seem silly today will appear.

Bicycle generator

During World War I, it was not easy to get enough electricity on the battlefield, so the Germans invented a two-person pedal generator, which looked like a two-person bicycle and mainly provided electricity for lighting equipment in trenches. This kind of artificial power generation device seems to be very successful, so it was continued to be used to supply power to radio stations in World War II.

Manned kite

During World War I, the main role of the Air Force was to carry out reconnaissance missions. In addition to using airplanes, the British also invented manned kites to spy on the enemy from high altitude. Compared with manned balloons, this manned kite is more difficult to shoot down. Manned kites usually consist of a string.

Kites can fly to the height of 100 meters to observe the enemy's situation and make some simple manipulations, and the number of kites has a great relationship with the weight of scouts.

Invisible camouflage suit

From19th century to the beginning of 20th century, military uniforms of various countries usually use bright colors to distinguish friendly forces and avoid injuring themselves by accident. For example, the uniforms of the British army have been red for many years, but this will make it easier for the enemy to find the target and aim at shooting. Before the First World War, it has been found that when the battle developed from a slow-paced battle in the past to a more intense sports war, military uniforms with similar environments had more advantages in the war. So during World War I, countries began to develop stealth camouflage.

In new york, USA, a group of sculptors and painters participated in this design. Some women wearing these invisible camouflage clothes hid in the rocks and grass in the park and were used to test whether these clothes were effective. Later, British experts observed that gray warships were easy to be found in water, so they suggested painting bright colors and strange patterns on the hull to confuse German U-boats. So the team drew protection patterns on thousands of American warships, but unfortunately, by the end of World War I, 96 of these ships were sunk by German submarines, and less than 20 of them may have played a role in confusing the Germans.

Artillery observation pole

Sailors can climb the mast to observe the enemy, but army artillery obviously does not have this advantage. During World War I, in order to help the artillery correct the trajectory, the British army tied a long wooden pole to the carriage, so that the artillery observers could climb up and observe the enemy situation and the impact of the shells thousands of meters away.

Rolling bomb

During World War II, in order to break through the German Atlantic barrier, the British army invented a strange-looking roller bomb. These rolling bombs are more than 3 meters high. Driven by dozens of rockets, they can rush to the German fortress at high speed. After blowing a gap, allied tanks can move in directly. However, on D-Day, no trace of this magical weapon was found. Because in many tests before the war, this crazy wheel was always changing direction, which was really difficult to control, and almost hurt the allied officers and soldiers and photographers who participated in the tests many times, so the British finally gave up this imaginative weapon.
