The Anti-Submarine Helicopter is an air unit in Game Boy Wars 3, designed to combat sea units, particularly Submarines. It is poor at damaging anything else, has low fuel, and has lackluster defense that can be punishing against most ships, which have anti-air defenses. However, since it is remarkably cheap, it's nice support for the Aircraft Carriers, but any ship that wipes it out in direct combat will get extra Experience because of the helicopter's high attack power.
