     What is achievable EM beam confinement in degrees,
     mod distance and power? Truck mount and or orbital cannons...

   It would seem the biggest limit is power.  Lasers are EM and can burn
   things and reach the moon.
   You're going to want to have ways to detect what is around you before
   too much aiming of high powered microwaves near human bodies.
