US Navy Aggressor J-10 S

An aggressor squadron is a squadron that is trained to act as an opposing force in military wargames. Aggressor squadrons use enemy tactics, techniques, and procedures to give a realistic simulation of air combat (as opposed to training against one's own forces). Since it is impractical to use actual enemy aircraft and equipment, surrogate aircraft are used to emulate potential adversaries. The US Navy and Marine Corps use the term "Adversary" to describe their similar squadrons. The first formal use of dissimilar aircraft for training was in 1968 by the Navy Fighter Weapons School (better known as "TOPGUN"), which used the A-4 Skyhawk to simulate the performance of the MiG-17. The success of formalized Dissimilar air combat training (DACT) led to transition of Navy Instrument Training Squadrons equipped with the A-4 into Adversary Squadrons at each master[clarification needed] jet base. The USAF followed suit with their first Aggressor squadrons at Nellis AFB equipped with the readily available T-38 Talon.

US Squadrons
Some US aggressor camouflage schemes emulate Russian markings, such as the multiple shades of blue and gray on this US Navy F/A-18.

Aggressor squadrons in the US armed forces include the USAF 18th Aggressor Squadron at Eielson AFB, the 64th and 65th Aggressor Squadrons at Nellis AFB, the US Marine Corps' VMFT-401 at MCAS Yuma and the US Navy's VFC-12 at NAS Oceana, VFC-13 at NAS Fallon and VFC-111 at NAS Key West, as well as the famous "TOPGUN" Naval Fighter Weapons School (US Navy) which is not a squadron per se, but operates F-16A and F/A-18A/B/E/F aircraft as part of the Naval Strike and Air Warfare Center (NSAWC) at NAS Fallon. With the exception of the NSAWC aircraft, all the US Navy and US Marine Corps adversary squadrons are Reserve Component units and aircraft belonging to the Navy Reserve and the Marine Corps Reserve.

The USAF also operated Aggressor squadrons in the UK and in the Philippines. The 527 AS was a USAFE unit that first operated out of the former RAF Alconbury near Cambridge, England, then later from the former RAF Bentwaters near Ipswich. The 527th initially flew F-5s, then later switched to F-16s; and trained over the North Sea and in Germany, Spain and Italy. The PACAF counterpart, the 26th Training Aggressor Squadron, operated F-5s out of the former Clark Air Base near Angeles City, Philippines.

Yeah i copied it from Wikipedia. i ve removed the markings from this J-10 and painted it in USN Aggressor Camoflague .
