Bear in mind, though, that we are talking about 31st-century beam weapons. The orbital lance in use by the Gamm faction in today's strip does not suffer from appreciable dispersal problems, thanks in part to an extended gravitic tunnel that shapes the particle beam while imparting near-cee velocity to the particles fired.
The non-discriminating reader of science fiction should look at today's strip and say "whoa... cool. I gotta get me some of that."
