DSII: counter battery radar figs

Is GZG ever going to produce an counter battery radar vehicle (and, to
me equally importantly, release it in the States)?

If that's not going to happen in the forseeable future, does anyone else
have a recommendation for who makes good figures?  The Stan Johansen one
looks OK.  Any other suggestions?

Also: how much artillery do people typically use, in terms of number of
vehicles relative to the number of other troops on the table, on board
or off, heavy, medium, or light, HEF or MAK, etc.?  Thanks!
