HMLA-773's lineage began in June 1968 when Marine Medium Helicopter Squadron 765 (HMM-765) arrived at Naval Air Station Atlanta with 7 officers, 12 enlisted men, and a single Sikorsky UH-34D helicopter.  The Squadron grew rapidly from this inauspicious beginning and in July of 1971 transitioning from the venerable UH-34 to the Bell UH-1E "Huey" and being re-designated Marine Light Helicopter Squadron 765 (HML-765).  During this period HML-765 was the lone Marine Helicopter Squadron selected to retain the Gunship mission. On 1 July 1976 the Squadron received its first single engine AH-1G "Cobra" (now on static display at the NAS Atlanta front gate) and the Squadron was re-designated Marine Attack Helicopter Squadron 773 (HMA-773).  In late 1978, HMA-773 transitioned to the twin engine AH-1J "Sea Cobra", an airframe that the unit would utilize for the next fourteen years.  Throughout the following decade HMA-773 refined its war fighting skills through a myriad of training and operational exercises.

In November 1990 the Citizen-Marines of HMA-773 were the first Reserve helicopter squadron to be activated and deployed to the Persian Gulf in support of Operations Desert Shield/Storm.  While embarked aboard the USS New Orleans and USS Tripoli, the squadron distinguished itself with mine sweeping escort and combat missions during the war.  In recognition of their exemplary performance during the war HMA-773 received the Navy Unit Commendation.

In the fall of 1992, the squadron received eight, state of the art AH-1W "Super Cobras".  With only a short time to transition to this radically improved weapons platform, HMA-773 embarked on an accelerated training regimen for all pilots and maintenance personnel in order to support two back to back regimental level Enhanced Combined Arms Exercises (ECAX's) at Marine Air Ground Combat Center Twenty-Nine Palms, CA.  In November 1993, HMA-773 began receiving UH-1Ns and personnel from other disestablished units.  In October 1994, having re-designated as Marine Light Attack Helicopter Squadron 773 (HMLA-773), the squadron mirrored the active duty HMLA structure enabling rapid total force integration for current and future combat and contingency operations.

Since reorganizing, the "Red Dogs" of HMLA-773 have deployed on numerous counter narcotic operations throughout the United States, Caribbean, and West Indies.  In May 1995 the Squadron deployed to the island nation of Antigua for the first in a series of "Weed Eater" marijuana destruction missions.  Further eradication missions followed on the islands of St. Kitts-Nevis, St. Lucia, Trinidad-Tobago, Grenada, and Nassau Bahamas.  HMLA-773 counter-narcotics missions in the United States included joint operations with the Army, Coast Guard and several US Law Enforcement Agencies in Kingsville and El Paso TX, Naco AZ, London KY, West Palm Beach FL, and El Centro CA.  In the space of two years, the Red Dogs aided in the destruction of over $20 billion worth of illegal narcotics.  Proving one of the Marine Corps mottos, "in any clime and place," in March 2002, the Red Dogs deployed with two Cobras, two Huey's, and 60 Marines and Sailors to Lundamo, Norway.  Participating in "Operation Battle Griffin," the Red Dogs took part in the second phase of NATO exercise Strong Resolve 2002.  During Battle Griffin, HMLA-773 was the only reserve unit to participate and demonstrated the unit’s ability to rapidly integrate with active components and NATO allies.

In 2002, HMLA-773 and HMLA-773 Det A based at NAS Belle Chasse LA, combined in order to form one complete HMLA squadron capable of fulfilling any assigned HMLA mission in the Marine Corps.  The current squadron organization is structured to maintain 2/3 of the Squadron at NAS Atlanta and 1/3 of the Squadron at JRB Belle Chasse.

Following the September 11th attacks, HMLA-773 prepared for action in the Global War on Terror.  The Squadron focused on preparations for combat operations in both Afghanistan and Iraq as training continued with an emphasis on desert and mountain combat techniques.  In October 2003, HMLA-773 answered the nation's call by deploying to Bagram, Afghanistan, and conducting combat operations along the international border between Afghanistan and Pakistan.  The Red Dogs served continuously in Afghanistan through April 2005, becoming the longest serving Marine squadron in a combat zone since the war in Vietnam.  In addition to combat operations the Red Dogs instituted ‘Operation Red Dog’, in which the Marines and Sailors of the unit gathered school supplies and other humanitarian items and distributed them to the local population.  Upon their return to CONUS the unit supported relief operations in the wake of Hurricane Katrina and was recognized with the ‘Marine Light Attack Helicopter Squadron of the Year’ award for 2005 as well as a Navy Unit Commendation.

 During June of 2007 members of the squadron volunteered for further service in the Global War on Terror and were deployed to Al Asad Iraq from September through January of 2008.  The unit was recognized again as the 2008 winner of ‘Marine Light Attack Squadron of the Year’ and also received the Department of the Navy Safety Excellence Award.

 The Marines and Sailors of HMLA-773 proudly serve our nation in peace and war. Ready, willing, and able...Fit Via VI!
