Guard don't do elite anything very well, I'm afraid.
Guard are very slow moving. There are a few things that get around quickly, but not much.
With what you have, you're looking at...
Russ, with Chimera escort, probably with
CCS inside to issue orders to speedbump Veterans on the ground. Everything moves about 6" per turn, to maintain firepower. Take Voxes, and lots of ranged firepower upgrades. I'd suggest keeping one unit of Vets dirt cheap. Like, 3x
GL, a Bolter, and Vox. Take an Auto Cannon if you have the points, there are orders that will allow the
AC to move and fire "effectively". The other Vet Squad could have a trio of Plasma, a Vox, and a Bolter. They'll be a target, so if you can afford Carapace, to get a save against Bolters it would be a good idea. Heavy Weapon if you have points.
AC for cheap is worth while as an attack of opportunity weapon. You might want Carapace on the
GL squad, also, but leaving it off makes your opponent consider targeting the squishier unit rather than your expensive guns. Similar thing goes into your
CCS. No more than 2 weapon upgrades, and a Vox. The Cadian Supplement has some neat relics, related to orders. Fancy guns make the Chimera a target... more important target, anyhow. Cheaper guns leave your opponent wondering if he should bother taking out the Chimera, when the Russ is dropping bombs. Or Plasma. Advisors are generally a good value, even the
MoO can be worth taking, as you'll likely sit still for at least one turn... Russ could be cheap, like an Eradicator with Lascannon and Plasma Sponsons, for about the same price as a
LRBT, or you could get more expensive / specialized. That group will cost about 450 points.
Valkryie would be better as a Vendetta, with the Scions + Commie inside, if you want to use the Commie. Or put the Commie with the Vets, to make sure they can tarpit a little bit better / pass orders better. The Vendetta probably has enough space for the Scions inside. I recommend Plasma with the Scions, as it best matches the abilities of their "basic" weapon. You're suiciding in, or stealing an objective. Either way, more shots, or longer shots is best for them. Honestly, I'd probably leave the Commie on the shelf. Without the Commie, you're looking at about 260 ish points.
700 points. Not super elite, and sadly, not super effective. My view on
IG, is that I started 7th with
IG with a near-perfect win record in 6th. I started getting creamed. I started using allies. I started using more allies. I started using
IG as minor allies. I stopped using
IG, and just played my "allied" army instead.
