|Since this is in the sci-fi topic, what kind of weapon do you see becoming the standard infantry weapon for the average soldier?
To me, laser, or particle beam weapons seem like just a fantasy mind extending to the standard-issue rifles we arm our troops with today. Try to imagine what a Middle Ages dreamer would think of if he applied his imaginings to the typical armament of a warrior in the pre-gunpowder era. He'd probably imagine some type of bow and arrow that could shoot multiple bolts at once, or a sword that could magically change length and even width, such that the functions of sword, spear and shield would be encompassed in one weapon, thus lightening the load to a warrior.
It seems unlikely that such a dreamer would envision the gunpowder weapons that revolutionized warfare.
What will the next revolution be?
