" There had been an army in which that sort of thing was done, a strong quasi-memory told me. The Marxist POUM militia in the Spanish Civil War, early twentieth. You obeyed an order only after it had been explained in detail; you could refuse if it didn’t make sense. Officers and men got drunk together and never saluted or used titles. They lost the war. But the other side didn’t have any fun. "
― Joe Haldeman , The Forever War (The Forever War, #1)
