[DSII] Light Infantry

Light Infantry--this is the one real spot missing in my NRE OBs.  There
isn't room to add any in the Tagmatic forces (Other than the Varangians I've
already got), but the Thematic units offer some potential for various types of
light infantry. Now, these carry all sorts of additional designations in the
Real World, principally Airborne, Air Assault, Mountain, and a host of
traditional ones (Jaeger, Rifles, Fusiliers, whatever) which have no real
meaning. However, going over various OBs, I'm a bit unsure on the difference
between Mountain, Abn, AA, and just plain vanilla light infantry. *Dodges
brickbats from the airborne types* Yes, I know they have slightly different
training in how they get to work, and the Air Assault TOs have to include
enough helicoptors to flit from here to there. This doesn't, however, seem to
have much effect on the way they are organized, nor does it have any effect at
all on a Dirtside or Stargrunt table (unless you airdrop them in, in which
case it can be interesting). So what I've been considering was to put together
a generic Light Infantry TO&E with the caveat that they might have additional
designations if one of the three
listed above.  Side note--I've worked out a tenative TO&E for a brigade
based on US practice (plus support assets at brigade level which don't exist
in US, but which get attached if a brigade goes off on an independant
mission), and noticed that it calls for over 200
hummer-analogs.  Not that light, is it?
