i keept thinking.. (yes, i also tried to cramp more than 2 MHMG in an army.. and now even with air-strikes.. very tempting
)
your army has air strikes & 3 MHMG, which is some good punch
on the other hand,
you have 18 grunts, which seem enough. but they donīt have any heavy weapons, just 1 sniper.
the air-strike is fickle and may well only hit 3-5 models _if_ it hits. not bad, but you pay for this by using:
3 M2 MHMG-- despite the inability to storm a position, the question is, if it is really _that_ effective?
by blocking the LOS with quick troops (e.g. the K9) you can target them with rifles/quick MHMG
the same is true of course for faster MHMG, but they can move to a position to attack and donīt wait for their opponents (and have more than 2 wounds!, just saw that...).
to move the guns around, i think you have too few grunts to act as shields.. the average vehicle can move ~3 times faster....
your guns need to shoot not move..
also, you can storm your postion. if you manage to take out 1 or 2 guns, chances are, that your W6+ models survive..
e.g.: cybertronic
1 OOS
1 diana
2 4+1 chasseurs+sniper
2 4+1 PV with smoke
2 EDD AV
747P
this army would mostly avoid the air strikes (at least the EDDīs)
the EDDs can easialy smash your army, i beg to think...
*edit*
(my point is not that cybertronic could do it, but 2 strong vehicles, e.g. strike skimmer or even 4 necromower)
either they move, stand & retreat (RC11, at 12-124ī! they shoot RC11/14 -> ~3 hits ~2 dead grunts each/round)
and after killing the shilds, the guns only have 1 W. not to forget the 18 cyber grunts.
ugly, but this tactic works if the oppontent can not storm 2 big vehicles that are ~>12ī away..
i belive your army can only relay on wait, and this is faild. you can not move vehicles (even if your oponent has only 2) around corners & shoot 2 actions and retreat or 3 actions (2 with +3 RC!!). this will smash any grunt unit. if there is nothing to return the damage (like grunt HMG, vehicles..) and only 3 guns which may not have LOS.... i donīt know...
==> in the end, i belive your army sacrifices to much to cramp 3 T85 (MHMG) & the air-strikes inside..
