Nothing says I love you like 7.62
7.62x39mm, as seen in the RPD, SKS and then the Automat Kalahsnikova?
7.62x54R, as featured in the Mosin-Nagain 1891 and its descendants, SVT-38/40, PK machine gun, and SVD/SVU marksman rifles??
7.62x51mm NATO, as (widely) seen in the hands of squad marksmen, snipers, and medium machinegunners?
or
7.62x25mm Tokarov, as seen in the TT-33, Cz 52, and several Soviet submachine guns?
:)
With regards to the 1918 BAR and its accuracy, it was NOT an "area effect" weapon. It carried only 20 rounds in a magazine, and spraying indiscriminately would quickly run you dry. At the time of its introduction the standard infantry rifle was the 1903 Springfield. It fired the same round as the BAR (.30-06) but with a far lower useful rate of fire owing firstly to the fact that it was bolt action and secondly that it only held 5 rounds, internally, and had to be charged with clips. The BAR supplied serious firepower for the day by being a self-loading rifle with 20 rounds in an external, easily swapped magazine. The 1918 and 1918A1 were both select fire, with a semi-automatic option, in which they had fine accuracy. The 1918A2 was a World War 2 model. The job of self-loading rifle had been taken over M1 Garand, so the whole idea of wanting a squad level heavy duty rifle that could quickly lay down that kind of fire was obsolete. As a result, the A2 did away with the semi auto feature, and only fired on automatic. Two different rates, true, but automatic all the same. It was intended to be fired from prone at all times (came with bipod) and to be used as a highly portable machine gun. Which it wasn't good at due to the small magazine.
Basically the problem is that the game has saddled us with with the full-auto-only feature of the 1918A2, does not model recoil so even the first shot won't hit anything further than 20 feet away, doesn't let us go prone to use the thing's bipod for improved stability, OR give us the entire infantry squad around which the 1918A2 was conceptualized (to cover us while we reload).
(I really really wish games would get past this concept that anything which fires on automatic is a melee weapon; machine guns score hits just as far away as the grunts with their rifles. But that's another gripe.)In game terms, it's relatively powerful, but only at ridiculously short ranges. The kind of ranges where I might as well pull out my 12 gauge and put slugs into their head, which has the same general effect for vastly less expense in ammo and maintenance.
I tried modding it to fit my ideal, but apparently you cannot have a weapon be semi in free aim and burst in VATS. Either it's automatic or it's not, and the burst length seems to be tied to the basic rate of fire. I'm pretty sure it would be overall more useful if it was semi auto only with decent (0.5) accuracy. I think I'll try that and see if I like it.
