The Depth Charge Emergency Ejection System is a GDI system developed to deal with a critical weakness in the GDI Mastodon. The Mastodon's main weapon, though deadly, had a rather limited forward firing arc, meaning it is unable to retaliate against swift foes who closed in on its flanks or rear. This was partially offset by deploying Mastodons in groups where they can provide overlaping fire for each other.
