[SG] Hammer's Slammer's Weaponry

Now that GZG has thoughtfully put out Hammer's Slammers vehicles,
does anyone have any thoughts on how infantry small arms
powerguns translate into Stargrunt?

I assume any data for DS vehicles
(http://www.geocities.com/Area51/Station/3565/slammin-the-dirt.html)
may be taken as canonical?

The major complication, as I see it, is that (according to the
books), the powergun discharges ALL its energy on the first thing
it hits (eg, a leaf). Would infantry carried powerguns have
difficulty penetrating any sort of cover?

Always questions. . .
