"1) The Winchester, I'm assuming, has little more than it's basic scope. Meanwhile, the MacMillan can be equipped with an adjustable bipod, an optional sling, a Mk 4 3-10x40mm M1 Mil Dot scope (translated as super fucking precise), and the .338 Lapua Magnum round, which is a significant bit larger than the .30-06 Springfield."

I think for this match the the Winchester has the Unerti 8x scope, I'm also pretty sure they came with slings.

The Winchester is also about half the size of the McMillian which means that it is easier to move with. Which assuming a meeting engagment with peer level opponents is super important. In other words while the Tac-338 works best a stationary crew served near anti-material weapon. The Model 70 may well be the better choice for an actual field weapon.

"Also; I really shouldn't have to explain this, but fine. The M4A1 has a more compact shape for urban battlefields, has apparently a larger magazine, and can be equipped with a wide variety of optics. The Sig is significantly more advanced, but there is a key difference that should be realized; it's got a helluva lot more bullets than Hathcock's Colt. Noticing the trend with weapons?"

The M4 also has the shorter range and less muzzle velocity, meaning less power.

"2) Yiu can't just ignore the argument about the men's training; it is, after all, a pretty important factor."

In general you're not wrong. In this case however I don't feel it's appropriate like Kyle in the context that we do on this site.

"3) Just to be clear; are you actually trying to beat the fairness challenge, or simply try to make sure the proposal is done right?" 

A bit of both I guess, though while perhaps a bit one sided I don't think its unfair enough to mentions. Even if I don't think it should go forward for other reasons.
