I do like the SHAAK from Barnes trilogy as well, although he also had another type of gun called a NIF (Neural Induction Flechette) which could be lethal or non-lethal and the flechettes could cruise around an area for a period of time searching for targets...

Information Unlimited has plans for a CO2 laser that conceivably could be shoulder mounted, and its of sufficient power to punch through steel

any wave guide would have to be able to tolerate the energy density of the beam without degradation. For temporary blinding, high temp fiber optics would suffice, but any higher power and you'd need something else.

Its easy to make a silenced flechette gun, you just need the permits to do so. Making a .22 bullet with a micro turbine engine or solid state solid fuel rocket thruster elements on its surface would do the trick. Guidance is the tricky part though, you'd need an AI guided laser designator for the bullet to home in on the target.

I think that developing a .22 caliber warhead of this type would be a highly profitable means of pushing nano-micro technology. You essentially want to miniaturize a Maverick warhead by a factor of a couple thousand.
