They could be legit, but...I dont recognize a single name on their staff as having been a player in that field. Doesnt mean they were'nt, just that they dont have the creds I would look for.
Website looks a bit hokey,but then not every outfit can afford a web-designer, I suppose.
If you're looking for work in that area, I'd strongly recommend Vance International, or any outfit currently being run or operated by Maj. Skip Flanagan. Have worked for him in the past- he;s the real deal, knows his sh *t, and is a true professional. No-nonsense,etc. Best Topkick I ever worked with-in or out of the Army.

If you do find what you are looking for,there, just be prepared- lots of travel, lots of action, and dont plan on being married.
