Command Vehicles

Any suggestions on how to make a nice looking command vehicle for DSII?
I'm working on some plastic Fortress Figures minis, and I wanted to make
one of them into a relatively distincitve command post.  The figure
looks
something like an M113 with a hoverskirt and a small dome centered on
the
back of the roof.  I can, and will, add some antennas but I can't think
of
anything else to put onto it.  I was thinking about a radar dish, but I
don't have anything small enough and I've got nothing to scratchbuild it
with.

Any ideas?
