1500pt IG for RTT

[Polonius]

So, I play a lot of IG, but I think the last 1500pt game I played competitively was about five years ago. Here's an attempt at what I hope will be a tough list for the following scenarios:

CCS, plasma x3, medic, Astropath, Chimera

vets, melta x3, Chimera
vets, melta x3, Chimera
vets, melta x3, Chimera
vets, Plasma x3, Lascannon, Chimera
vets, melta x3

PCS with flamer x4
squad w/ AC&GL
squad w/ AC&GL

Valk w/ Rocket Pods
Vendetta

Hydra

All chimera hulls have heavy flamers, and the PCS rides in the vendetta while the melta vets ride in the valk.

Looks alright but i make it 1540 pts though :(

[Polonius]

That's weird, because when I double checked it comes out to only 1480....

[MC Tic Tac]

lol maths fail I got 1475 this time lol

You should be safe then lol.

Can't see the sense in the Medic and/or the Astropath, you could fit another squad in or even another chimera for the foot slogging vets IMO.

I get 1480!

For the 20 more points: heavy bolters on the valk, and melta bombs on the infantry squads.

Medics good with the plasma CCS, but still pricey,
remember you can give ordered FROM a chimera, but not to a unt IN a chimera.

I think you need some sort of S8+ large blast in your army. Right now you've go great close quarters anti-mech, but nothing to death with Armour 3 once its out of its vechile at range. Even a collossis or griffon would be a fantastic addtiion to your force.
