A new SG2 Weapon?

Okay, I've been thinking about the comments that flew back and forth 
regarding the laser-ionizes-air (I still don't think a laser would make
a 
"crack" sound in atmosphere) thread and the charged beam thread and
something 
just snapped last night and put the two together, so I offer for 
consideration the following:

The PLEBe Gun (that's Portable Laser/Electron Beam Gun).

When the trigger is pulled, a "precursor" laser is fired that ionizes
the air 
along the laser's path, then a microsecond later the electron beam goes
off, 
following the positively charged ionization trail that the laser leaves 
behind.  If there's no atmosphere, the laser function can just be shut
off or 
ignored.

Firepower 12 
Impact d12 x 2 (or maybe just d12?)

The firepower is like a laser, since it's a really fast/straight beam
that 
makes targeting relatively easy.

The impact is d12 x 2 vs vehicles and PA troops because the surge of (-)

charges on the target could cause significant problems with electronics,

which are essential for most of these kinds of items to work.  The PLEBe
Gun 
would therefore combine the damage values of the HAMR (against "hard" 
targets, anyway) with the accuracy of the sniper laser.

And this weapon would make a very loud, lightning-bolt like "crack"
sound 
along with leaving a visible trail--not a good sniper weapon (reveals
your 
position), but good for other purposes!

And, flick-a-switch and the weapon just uses the laser for a
designator...

Just an idea.
