Army Tank Ace or Army Tank A-Spec refers to an a-spec individual who's dedicated to fighting against ace exclusion and for the inclusion of a-spec individuals in queer spaces.
History
Wiki user -lolbidiot-gae- created the term on June 5th, 2021, after seeing the A-Spec Exclusionist page.
Flag
The purple stripes are a combination of the a-spec flag and the inclusionist flag. The tank is to represent the fight for ace inclusivity, and the flower is the inclusionist symbol.
