I have used one Warp Hunter before, but today I brought 3 in a 2k list.
I never used the 72" Str D, 7" Blast shot, but with the regular profile of each tank shooting d3+1 Str D Barrage, blast (-1 on the D table) it was wrecking time!
That is 6-12 D barrage blasts/turn!
I had one turn of shooting with over 27 3+ rolls on the D table and another turn with 23!

Expensive unit/formation at 600pts (they each had the Holo-Field upgrade), but controlled their half of the table!
