Glad to hear the list is on the right lines, to answer some questions:
1. Where is the mek going? Well if I am honest it is a toss up between the trukks/bike flank force or just going with all the boys/grots to give them some cover as they advance, may need to play test to see which is more suitable.
2. Whats the plan for the kommandos?
Well, that depends on my opponent truth be had, if its an gun line, you can bet your teef they are going to appear as flanking. I do like the sound of burnas....may switch em.
3.
KS on bikes?
That unit is designed to get to the flanks and

it up.
Pks, yeah they are good but 5 s5 templates put the fear of god into people as I have learnt, its good for clearing out any pesky gunner units in a bunker, destroying a hoard and most of all
ks are cheap as chips (5 points...)!
4. why not drop the special weapon on the boyz to give their trukks boarding planks?
I don't expect the trukks to last long enough for
BPs to be effective, the
SB upgrade is only there in case they hit the troop lines or some poor soul gets caught in the open in the trukks path.
Looking at the list now, I am still playing around with some things, one of which being the grots. tempted to drop them and the power fists on shootas for a few deff koptas... but I lose a meat shield....hmmmm thoughts?
