Phipps that's silly, stupid and arbitrary. There's no rule in SR4 I've seen yet which stops you from using those weapons or calls for a different definition than that in the main book, which was the answer to the OP's question. Another way to view it is... many people are trained in small arms, but only those w/ military (especially infantry) backgrounds are trained in the use of heavy weapons. (MG's, GL's, missile/RPG, etc....). "Weapons bigger than an assault rifle..." is how the book calls it and it makes a lot of sense and produces a good catchall skill which isn't in the firearms group.
The point of that portion you quoted... was THAT THE M1919 .30 CAL BROWNING WAS A CREW SERVED WEAPON NORMALLY MOUNTED ON A BIPOD OR TRIPOD!!! (emphasis needed, as were the german infantry MG's), But that with proper training it could be used on the move and for room clearing operations. NEWS FLASH, most crew served weapons can be operated just fine w/ a single person. The purpose of the crew is primarily to carry extra ammo, provide a backup gunner, spread the load out and reduce risk in other words. But this is SR... where we use drones to carry extra ammo and parts, or just mount the heavy weapon on the drone. Then we fall into the other problem with your post, all vehicle mounted weapons fall under another skill... Gunnery, even the ones which are manually aimed and fired, such as a MG mounted on a pintle in a jeep.
All you've done w/ that careless & stupid definition is remove MG's, GL's, missile/RPG's, and AC's from heavy weapons leaving it with.... nothing! I'm guessing that it's because you'd rather they fall under skills in the firearms group so you don't have to actually train heavy weapons. Right now, HW pretty much encompasses all the belt-fed guns and all the man portable explosive weaponry. You take that away and you might as well just train archery (lord knows a trollbow w/ the 8str/8bod requirement above is probably cheaper and preferable to the panther cannon right now).
Well, perhaps "effectively" should have been "efficiently" in my original comment.
As for the rest of it, there is a large difference between a modern LMG with rifle stock, magazine well for backup, and a bipod and a 1919A4 WWII vintage belt-only GPMG ("light" was a mindset more than a reality back then). The fact that many of the new LMGs (or perhaps more correctly, Sustained Fire Rifles) aren't even belt fed anymore means that they're a lot closer to an AR with a heavy barrel and bipod than the ol' Ma-Deuce on the top of a Hummer-equivalent.
Furthermore, I have exactly zero military experience and I was able to fire my buddy's HK21 just dandy, thanks. It's feed is a bit different but it's far from impossible to pick it up when you have a bit of rifle experience to fall back onto. I was also reasonably accurate for an untrained idiot once I got used to the fire rate with 5-6 round bursts hitting man-sized targets with multiple rounds at 300m more often than not. Say, 30 minutes or so of practice total.
A machinegun isn't some magically incomprehensible "Holy Shit! I can't possibly use use this thing at all because I've only fired ARs in the past!" weapon, dude.
My main issue with the "Heavy Weapons" skill is that it covers a ton of weapons from GLs to Artillery. Sorry, but that's a bit of a stretch for this kid. I also have an issue with
any vehicle mounted weapon being used with "Gunnery" from some ganger duct taping an AR to a roll bar of a beater Toyota to an Ares electro-kinetic tank cannon.
