Corporal is an enemy from Crisis Core -Final Fantasy VII-.
He dons the red bandanna found on officers of Shinra's army. Single attacks deal enough damage to defeat this enemy without problems. If the player is doing in the "50 Shinra Troops" mission however, Assault Twister+ will come handy, because as many as nine Corporals can surround Zack at once.
Corporal is a military rank in use in some form by many militaries and by some police forces or other uniformed organizations.
