In case anyone is interested, one of the rifles they're talking about
here, the
Heckler & Koch HK416, is the gun carried by Beau Lorne on the
North Carolina in my original novel. In case anyone was wondering why I choose the throwaway things I do when writing; this is why research is important. The HK416 is currently carried by Delta Force; Beau is Delta.
I hadn't heard about the
FN SCAR before, though. I also haven't established what rifle the Rangers onboard carry. I've mentioned that the Air Force carries
FN P-90s, but that's less a matter of research and more a matter of me stealing from Stargate; I doubt I'm going to stick with the P-90, if only because it's not currently used by the U.S. and doesn't have anything that makes it stand out from other rifles. I haven't said what the Marines and the Navy carry, either, although I've probably used the
M16 and
M4; I just don't think I've made a big deal out of it.
Of course, since Delta can carry basically anything they want, I've also mentioned that along with all his luggage, Beau also brought a ton of different weapons, at least one of which is a Vietnam-era
CAR-15. How do I know this? He made Colby shoot with it in a scene I've written. Why the CAR-15? A mention in
Black Hawk Down, about a Delta operator carrying a Vietnam-era CAR-15 because it makes bigger holes than modern weapoons.
If anyone was wondering how I did research and made decisions. Which they probably weren't.
