The Punching Glove is a glove that springs out of a bag when you're near enemies. This can be used as a secondary melee attack. Marco and Tarma used the Punching Glove in the First Modern War and Second Modern War. In Metal Slug Advance, instead of using a regular knife, Walter Ryan uses this Punching Glove. Ralf and Clark also use a glove that comes out of their neckband (because they don't carry a backpack) in Metal Slug 6. To use it however, you must go into a crouch while near an enemy. Note that Ralf is the only character that is able to damage tanks with his melee attack.
