The Marine Diver is an enemy in Metal Slug 3. They are a special aquatic unit used by the Rebel Army during the Third Modern War.


The Rebel Marines used these suicide divers, with the objective to secure the destruction of the Slug Mariner when battling underwater. They carry an oil drum on their back, which they will detonate when they get close enough to the player. They frequently dive in small groups, increasing the probability of damaging or destroying the player's vehicle. They are one of the most loyal troops of the Rebel Army: they are willing to sacrifice their lives to secure a better future for their faction. They receive one of the most special training from the Rebel Army, and make some preparation rituals before diving.
