Do military weapons have intellectual property rights? Isn't wartime a dead letter?

Intellectual property is only a kind of material protection for technology owners in peacetime. In a state of war, no one can care about personal interests, as long as they can be produced and used on the battlefield.

Infringement of intellectual property rights, compensation and suspension of production have become enemies, and you still have to struggle with this problem?

Afghanistan, the Middle East, Pakistan, Africa and all kinds of light weapons are produced in the world, but they are not delivered.
