[MilCom] Red dog?

[Stavro]

Early today I heard I think it was Red dog 41? I know it was Red dog as 
the call sign. .I am located in Saint simons island Georgia. The last 
time I heard this call sign was around the time of the 2004 Sea island 
summit. I remember someone telling me who used this callsign. But don't 
remember any more about who it was that I heard I heard the helo but 
couldn't get out in time to try to take a picture of it .. Steve
