What was invented because of the war? The more, the better. Urgent need! ! thank you

Computers are designed to develop strategic weapons and solve a large number of operational problems. It first appeared in America.

Rocket technology: The V2 missile designed by German scientist wernher von braun first appeared in World War II, and rocket technology began to advance by leaps and bounds after the war. The Saturn 5 rocket of Apollo program was also designed by wernher von braun.

Infrared imaging technology: It first developed from the night combat equipment designed for German Panther tanks in World War II.

Mobile phone; I think it first developed from individual hand-held radio and appeared during World War II.

Jeep: It first appeared in World War I and developed in World War II.

Jet engine of modern aircraft: It first appeared in World War II, and the German ME262 fighter was the first jet plane in the world.

Parachute: designed to solve the problem of pilots' escape in World War I.

Tanks; Designed to break the deadlock in positional warfare in World War I, it was first developed by Britain. German blitzkrieg tactics in World War II were also based on tanks, which were simple weapons.

Needless to say, artillery. . . . .

Simple weapons must have been invented because of war, such as military aircraft, missiles, various chariots, military ships, quantum weapons, microwave weapons, electromagnetic pulse weapons, biochemical weapons, precision strike ammunition and so on. Does the key landlord say that the bag does not include weapons, or is it just daily necessities?
