So, from the rulebook, grenades count as a weapon upgrade that can be used by every model in the unit. Also from the rulebook, weapon keywords add up. I.e. 5 Stormtroopers in a unit with the impact grenade upgrade, will throw (within range 1) 5 black dice with impact 5. Makes vehicles a lot more vulnerable to infantry at close range!
Seems to be a no-brainer for Stormtroopers to use grenades by the way for only 5 points, since it actually changes their attack dice to black at distance 1 or less. For rebels its a bit less of a no-brainer as their ranged attacks are already black.
