Good Post CP!

The Colony had MP5's.
The repaired Coast Guard Chopper had MP5's
Victor or maybe Marcus said there were rescue choppers in and out of The Colony's location early on.

So, let's tease this apart some more.

Would the Coast Guard be issued MP5s? I do not know. I figure standard side arm. With a special issue of long rifles if required. An MP5 would not be out of the question, but I do not know. Just sits wrong with me. I would want an MP5 in close quarters (SWAT) or trying to be discrete (Secret Service). But, damn, a sailboat. That is even more up close and personal than a building and I think I would lean towards side arm. Does the Coat Guard do close assaults or call for backup?

To make things more curious, one of the MP5's from the colony had a suppressor. Could be an addon, but the MP5 does have a suppressed model. This sounds even less like the Coast Guard.

Something about this chopper makes it stand out. The coast guard must have multiple choppers. Why would Thomas and Puck remember this number? Spec Ops under a "False Flag"? Not a false country, but a false agency. The CIA used paint some of the spy planes as NOAA; The National Oceanic and Atmospheric Administration. I do not know. I think the cause of this is conspiritorial. Not "natural" like a metorite in Night of the Living Dead, accidental release of virus (28 days later) etc...
