Agents of STRIKE
The SHIELD Quinjet is one of the most advanced troop transport vehicles in modern aviation. It is highly mobile, with VTOL capability and a top speed rivaling many fighter craft. It has decent air-to-air and air-to-ground combat capability, and can carry a full team of agents into an area of operations in concealment thanks to its stealth field technology.
STRIKE has access to a Quinjet, at a secret airbase operated out of Governors Island, New York. The island can be accessed by boat, or by a tram from the Crypt through a secret tunnel.
