Among the 6,200 airmen at Robins Air Force Base, you'll find a small population of a different breed.
The Marine Helicopter Squadron invaded the territory two years ago,
as a result of the 2005 BRAC process.
13WMAZ went Behind the Lines with the Red Dogs, a unit surrounded by Air Force Blues.
In early August, the roar of an F-15 blasted overhead, while Marine's tuned a Cobra helicopter near the flight line below.
The crew didn't react to the noise. It's almost as common to their ears now, as the spinning of the blades on their own choppers.
However, it may take awhile longer before their presence on Robins blends in.
Sgt. Luis Perez said, "Some people are intimidated or they just don't know, haven't really been exposed to us."
Perez is a safety inspector for the unit. He took a guess at why some people react to the Marine's presence awkwardly.
He said, "I guess it's the hype."
Maybe it's their pride.
Perez said, "Going above and beyond, never backing off."
He said the Red Dogs, a combination reserve and active duty unit, practice that mind set daily.
They maintain a fleet of light attack helicopters: AH-1W Cobras and the UH-1N Hueys.
The Cobras maneuver tight spaces with laser guided Hellfire missiles aboard.
The larger Huey transports troops and supplies. It's the workhorse of the fleet.
Perez makes sure both types operate without a hitch.
He said, "Basically, all the air crew and pilots lives are in our hands."
The Red Dogs perform the same mission tasked to the airmen at Robins. They protect, serve and keep aircraft soaring. They just go about it backed by the hard core, Marine Corp ways.
Martial Arts training matches, now a staple of all Marine training, happen weekly.
The thuds of bodies slamming mats are jarring to the by-stander, but routine to Sgt. Jason Gross. He calls it "fun".
Gross said, "There's a difference between hurt and pain. There's a certain amount of pain in everything."
He says that mantra took hold in basic training, all 12 weeks of it. It's the longest basic training for any branch of the service.
That difference, along with Marine customs, separate the squadron from the prevailing Air Force culture at Robins.
For the most part, Gross sees both branches as the same.
He said, "We all put on a uniform. I choose to serve the Marine Corp. They choose to serve in the Air Force. Were all serving the US Military. Were all serving the same purpose."
There are about 320 Red Dog Marine's at Robins, Half reservist and half active duty.
The unit came to Central Georgia from Dobbins Air Force Base in Marietta.
An interesting fact, their commander Lt. Col. David Steele, flew Marine One for President George W. Bush during his second term in office.
