Although some US marksmen have been using 7.62mm Magnum rifles there is hopefully no prospect of their being issued 8.59mm rifles. Believe a marksman as member of an infantry squad should be almost invariably armed with a weapon that fires the same ammunition - either 7.62mm NATO or possibly 5.56mm NATO - already used within the squad or platoon, and issued with match-grade rounds when available. It is also unlikely that any army would routinely weigh down a marksman or sharpshooter with an extended-range weapon weighing more than 10kg.

Contrastingly a strong argument that can be made for common but distinctive and non-‘bundled’ use of an extended-range MG by infantry companies when fitted with a ‘heavy barrel’, and by sniper teams with a ‘light barrel’.

My small army viewpoint is that 8.59mm is an awkward calibre for general use and inferior to a modern 7.62mm magnum cartridge such as the Winchester Short Magnum. However, thinking long and hard about the above post indicates that another viewpoint could see awkwardness as a goal and as justification. And if GD’s basic LWMMG proves to be both reliable and robust then it could in 8.59mm become a real goer for a large army.

Possibly some corporate or other has been reading Machiavelli and caused GD to seek multi-mode overmatch with its 8.59mm MG. The justification being that an opposing force with less capable logistics would be unable to field and support a large number of an extended-range MG intermediate between the usual 7.62mm and 12.7mm varieties. A possible response or reaction to that would be to succeed/replace a 12.7mm cartridge and MG by something a bit smaller and more portable that would nonetheless over-match an 8.59mm MG. However such a cartridge and MG would be in some ways inferior to the 12.7mm M2/M3 Browning and especially one with SLAP-type ammunition.

Ultimately the question of 8.59mm is just another iteration of the problem that affects infantry: how to rationalise and employ to advantage some family of modern rifle/MG calibres and cartridges. And it is finally apparent that small army and large army viewpoints could be very different.
