How many of you have ever shot a modern belt fed machine gun? Talking about a few hundred meters max range is just ludicrous. I'm better than that offhand with a 5.56 mm carbine with iron sights. The target is bigger than a truck, for Christ sake's. The reason most WWI kills were at closer range is very few of the pilots lived long enough to learn how to shoot accurately at range, and if you are actually being shot at you tend to move, quickly, unlike the game where you can trade fire at distances with steely nerves and little repurcussion to be hit.
The Spandau had an effecive range of 2000 meters which is probably more than the range of the same gun in the game, as it is limited to radar range and that seems to be about 1400-1500 meters. That's not the maximim effective range, that's the practical area target range with accuracy. Even the balky Lewis gun in it's .303 caliber stated an effective range just inside 1000 yards, and a maximum effective range of over 3000 yards.
The sights on a machine gun are set like a rifle, i.e. they are not mounted such that the eye and axis of the bore are parallel at all, but intersect. The practical application is that the bullet fires upward as the bore is aiming slightly upward to what the eye sees as level, so a gun (machine guns are properly called guns) sighted at 300 yards fires high at 100 and 200, even at 300, and drops away for each 100 after that. The drop becomes incrementally more extreme as the range progresses. However, the range the weapon is sighted to can level the drop if the gun is used most often for distant targets. Even a flat trajectory 7.92×57mm Mauser (the Spandau round) ony has about 8 feet of drop at 500 yards (around 100 inches, depending on the load) when fired "flat". Give me tracers and I'll drop every round on the target the size of an aircraft at 1000 yards after a couple bursts to range the target.
I agree there should be bullet drop, and have always said so, bit to limit the range to 300-400 meters is ridiculous. The bullet drop would seperate the shooters from the guys that lean on the fire button and spray. That's why I want the guns to overheat as well, cancel out the spray and pray crowd.
If the ability to hit a aproaching target is taken away, then this game defaults to win 8 turn supremacy.
