the guns...
The machine guns at the end of SPR (Browning .30 1919 air-cooled machine guns) were used throughout WWII, Korea, and even some in the Vietnam war as I recall reading...
They're extraordinarily heavy, they're a bit heavier than an M-60, have ROUGHLY the same ammunition size (.30 and .308...), and about the same firing rate. So, in essense, the M-60 and the tank-mounted .308 machine gun (whose name escapes me now but has been discussed more than once in here), are the current weapons in the 1919's role.
However, surprisingly enough, the M-60 shares more with the MG-42 that the germans used, than the 1919 browning.
(quick-change barrel)
the 1919 was designed after WWI, as a man-portable air-cooled medium machine gun. It was, essentially, a Browning 1917 medium machine gun with a new barrel. (the 1917 was also used in WWII. it had a water-coolant jacket surrounding the barrel, to keep heat down and firing time up. this made it *RATHER HEAVY*.)
the M-2 machine gun was designed (ALSO by browning!) in I think 1920 or 21, with a brand spankin' new round designed to punch through the early armored vehicles of WWI. (they would actually do quite a number of light tanks the nazi's fielded in WWII...)
It *CAN* be portable, and in fact was used by ground troops during desert storm. the "Portable" kit consited of a rather bulky tripod (carried by one guy, who also carries an M-16 or M-4 carbine), the M2 itself (VERY heavy, but can be "Hauled" by one guy) and the ammunition (again, very heavy.) so it's essentially a 3 man crew.
I beleive that in WWII they did have 3-man M2 crews as well, the tripod guy carried an M1 carbine, as did the ammo carrier, while the guy hauling Ma Deuce had a 1911a1 (yet ***ANOTHER*** John Browning weapon... heh). Though most common were the Browning 1919 crews. Also seen in SPR was the light machine gun included with most platoons - the Browning Automatic Rifle. (Yep. Yet another John Browning fave...)
It's suprising to me to this very day that all of our infantry weapons of WWII were designed by 3 men. Garand, Browning, and Thompson. (and Thompson took a few hints from Browning's designs, too.)
ohwell. Anyways, back on topic...
The M-60 is phased out of the military (or is still being phased out) due to it's high weight, low rate of fire, and Pain In The Ass Barrel changing, and the realization that a machine gun in 7.62mm NATO isn't neccicarily needed by ground troops, the 5.56mm is just as good at the ranges they typically work with, and can maintain a much higher rate of fire, and carry more ammunition. (smaller ammo = more ammo carryable!)
HENCE, FN's SAW and Minime are replacing the 7.62 M-60, just like the M-16 replaced the M-14. (it doesn't hurt that, with the M-60 out of the picture, logistics with supplying troops with 2 kinds of ammunition becomes eased.)
I think the only fielded 7.62mm weapon we have anymore is the Remington 700 that the sniper's use... and they don't exactly eat through ammo.
