Attack helicopters are helicopters that are armed with ATGMs ( look it up), rocket pods, and 20-30mm chain/miniguns. Two examples are the MI-24 Hind and the AH-64 Apache. They are used to blow the shit out of anything in range, including tanks, infantry, IFVs, and anything else unlucky enough to be near them ( unless the helicopter is an OH-58 Cayuse or an AH-6 Little Bird, in which case you are fine unless you manage to make it crash on you)
Attack Helicopter is a specific gender that was made fun of in 2014 as a transgender joke, but now several former Air Force members have come out as an Attack Helicopter/Apache Helicopter due to there sentimental attachment to their own helicopter. The pronouns are Heli/Copter/Helicopters. Though many members find this gender to be a very offensive joke, but what is really happening is the members of the Attack/Apache Helicopters are being oppressed by the people who are fighting against oppression. Though there is less than 100 people who identify with these pronouns, they are still a part of this society and are getting pushed out by the LGBTQ+ community.
Examples
“I identify as an Apache Helicopter.”
“You are a transphobic and you aren’t funny”
“But I have an attachment to my Apache Copter, and I identify as that now to show my thanks and connection to my copter.”
