PTW and I wanna my leman russ afterwards.
by the way, in the most recent edition of imperial guard codex, there is an Orders system. For example, one of them ("Kill it!" or something like that) give all squad's weapons "twin linked" (re-roll failed hit rolls). There is like four of them and you need to succeed a moral roll to make it works. Radios let you use Da Colonel's Cmd or something. Can't remember all of it.
EDIT: it has to be done from the top to the bottom of the command chain.
The Company commander can:
-"Bring it down!" make target friendly unit's weapons twin-linked (essentially sustained fire)
-"Fire on my target!" make target ennemy re-roll successful cover saves
-"Get back in the fight!" make unit regroup or stand up.
The platoons commanders AND the company commander can:
-"First rank, FIRE! Second rank, FIRE!" make guardsmen fire their basic lasgun once more than normal
-"Incoming!" Make the friendly unit going to the ground have +2 instead of +1 to their cover save. (yes, "DUCK TO COVER!" is a valid command)
-"Move! Move! Move!" make target unit roll three dices and take the highest when sprinting.
And taus DO have a rather shitty precision on their basic units. But otherwise tau tech is far better than imperial tech, stat wise. Of course, as an imperial guardsman, you shouldn't touch it, lest you call the wrath of imperial authorities upon yourselves.
Tau basic pulse gun: Range 30, strenght 5, AP 5, rapid fire (can fire twice at max range if not moving, once at max range or twice at half-range if moving, per last edition rules)
Imperial basic laser gun: Range 24, strenght 3, no AP, rapid fire.
Yeah...
