Military parade 阅兵

A military parade (square bashing in British military slang) is a formation of soldiers whose movement is restricted by close-order manoeuvring known as drilling or marching. The military parade is now almost entirely ceremonial, though soldiers from time immemorial up until the late 19th century fought in formation. Massed parades may also hold a role for propaganda purposes, being used to exhibit the apparent military strength of one's nation.
