(DS) Kra'Vak tanks.

I just got my order of dirtside Kra'Vak from GZG. While I am happy

with the order I do have a small problem with recognition. None of the tanks
packages were labeled. First, I got 2 packs of VTOL. As far as I

can tell they are the same ones.  How can I tell if they are DF-K05
Ko'TA
Attack VTOL or DF-K06 Ko'Iv Scout VTOL?
I also seem to have 8 different tanks even though the web site only

list 7. I have 2 packs of the larger size body, the one with the notched
front.  One I think is the DF-K02 Ki'Ca Heavy Grav Tank.  One has a
large
rail gun, the same size as the fixed mount guns on DF-K08 Ki'Rok Grav
Heavy Strike Vehicle. The other one has a smaller, offset gun on a square
turret. What are these? Thanks for any help.
