Matt's Imperial Guard house rules.

From now on I shall be doing the following for the sake of sensibility, and my sanity.

My command HQ shall be taking Kasrkin bodyguards.  Because it makes sense, even if not supported by rules for these elite to be guarding the commander.  And gives a reason to use the models, which are awesome.  Stormtroopers however are not.

This will bump the HQ base price from 50 to 80 (a slight premium considering they don't get deep strike or special ops).  For this they get Krak Grenades, Carapace armour, Hotshot lasgun and Hotshot laspistol.   Any veteran may replace his lasgun or laspistol with a power weapon for 10 points. They may not take a heavy weapon though.   But retain all other options.
The commander does not get the hotshot guns however.

Troops in valkyries/vendettas may disembark even if it is zooming, but they must do so by deep strike as per the grav chute instertion.  I'd say the same for stormravens aswell.

Leman Russ tanks that were stationary or moved at combat speed may always fire their turret weapon, which won't affect what other weapons it may normally fire, even if ordnance.  Note that you still can't snap shot blasts, so shaken/stunned is going to shut down the big guns.  But can only cruise at d6+6"

Atillery also doesn't generally make sense, but they are still potent.  I don't use them, so can't think of a way to fix them.
