Didn't occur to me while reading through any of the material earlier, but the weapon ranges seem very low, although this maybe just that I don't understand ranged combat properly. My first thoughts were:
Weapon Range Comment
Vulcan Pistol Short Seems fine
Flamethrower Short Seems fine
Vulcan Carbine Short 20 m range for a carbine - no greater range than a pistol or a flamethrower?
Vulcan Machine Gun Short 20 m range for what seems to be more like alight machine gun than a sub machine gun seems very low
Legionnarie Carbine Long 100 m range seems low for a standard military issue weapon especially one that seems to have had a lot of effect in the Third Horizon
Then I started to consider the -3 Beyond weapon range. This seems to suggest you can shoot a Vulcan Carbine out to about 100 m but won't a great chance of hitting anything. This seems about right. Of course you also seem to be able to fire a flamethrower out to that range which is hard to imagine and the MG still seems rather challenged.
We might want ranged combat to be less deadly than reality, particularly at range to avoid PCs being picked off at range by groups of relatively low level NPCs but some of this weaponry seems far less capable than what I imagine are its 20th - early 21st Century equivalents which seems counter intuitive.
