Brigadier Call

Usually when charging towards an enemy or rallying friends, family, or an army to save the day, there comes a time when the hero or heroine lets out a Brigadier Call, or a Charge Call.

A Brigadier Call is usually made by a horn or humming.

The classic Brigadier Call is usually played in baseball games or in an army.

There is also an Cavalry or Army Charge Call that is played when charging into battle.
