The
SM monster hunter unit in the shooting aspect is Grav cannon Centurion or Skyhammer formation Grav
Dev.
If you are looking for combat.
Imho, the best contender is
CM Smashbane, Hammernator, or Ironclad Dreadnought with
PF and Sesmic Hammer (the latter being concussive) Vanguard can do some damage with lots of power weapon. Just nothing other than
PF or
TH is satisfactory in putting wounds on T6+
MC, while in combat anything not carrying a
SS will be eaten by
MC quickly. But putting all those on
VV is going to make the squad expensive very quick. Will still vulnerable to
FW gunlines or even just hordes of Termaguants, and
HG have no way to get
inv save all by themselves....
Imho,
HG is better charging out of a Landraider rather than exposed a whole turn when disembark from Droppod, since they will be eaten by all the AP2 shooting like Plasma Cannon. So generally speaking, the
VV maybe better since their mobility are grantedby only 3
ppm.
A thought for you to make reference when building your
MC hunting force. Take a captain or
CM with artificer armor, grav pistol, burning blade,
JP, then take
VV 5men, one
TH/
SS, one
PF, two pairs
LC, and one more grav pistol and Power axe. Before charging in fire the grav pistol, hopefully one wound through to make the
MC I1, then the Captain attack with burning blade, should be able hit a few times and the
MC need to take blinding test which it most likely to fail as it is now I1, which make it WS1 so that
MC now swing last and hits your squad on 5+ while you just kill it with all
PF,
TH, and
PA.
