Roman cavalry would often have lifelike armored face masks which were deliberately expressionless to add to their creepiness. Conversely, traditional Japanese face armor is often contorted into aggressive displays of anger. Ironic somehow, since the Japanese are considered stoic and in control of their emotions whereas modern day Italians are caricatured as anything but. Military masks are interesting because they reveal the underlying hidden character of the often faceless uniforms of war. They range from early lifelike representations to some of the more abstract examples during the Renaissance or the accidentally terrifying arctic warfare masks of the otherwise friendly Swedish.
