Dive (or diving) is a command or function that allows a unit to vertically descend below the surface of the water, and become submerged. The opposite command allows the unit to surface, going back to be in contact with the air.

While dived, some of the units funtions may become unavailable, such as the Atlantis’s air staging.

Example of units that are able to dive:

• all types of submarines
• Seraphim T2 Destroyer
• Aeon Experimental Battleship
• UEF Experimental Aircraft Carrier.

Note that some units (like ACUs, for example) will always be sumerged if they idle or move on water. Those units do not have the proper abilities to "dive" or "surface".
