Anyways, allow me to detail a bit on possible equipment used during this game.
At least what I think should be possible.

Handheld weapons:
- [b]Standard firearms:[/b] They do their job just fine even in this time period. Cheap, easy to maintain and excellent for equipping the masses.
- [b]Advanced firearms:[/b] They use further refined ammo, propellant and gun mechanisms to keep up with the times. They are cheaper than other alternative but may be also approaching their limits.
- [b]Intelligent firearms:[/b] rocket/jet munition which seeks out its target, correct the user's aim and give other thankful additions. They are great but each shot could be quite expensive. If you wish to spend millions of dollars on a simple firefight this is the way to go.
- [b]Electronic Guns:[/b] Railguns, coilguns, whatever. The weapons would be costly, around 10 times that of a comparable firearm. Their advantages are velocity, adjustable performance and to carry cheaper and more numerous bullets at comparable weight.
- [b]Lasers:[/b] While scaling down X-FELs should be posible and somewhat feasible as anti-personnal weapons the costs would be horrendous. Currently a desk-sized X-FEL costs nearly a million dollars and that's just a research equipment. Besides, DEWs have poor damaging mechanisms so 5-10kj jolts would be kinda unsatisfactory for their cost. Maybe richer countries attempt to use these as "snipers" since there's almost nothing to make these weapons miss. X-Rays may also be used to disable unshielded electronics.
