So still new to the game and just wanted to clarify how grenade and similar upgrades work.
If I purchase concussion grenades for a unit of Stormtroopers is it added as a weapon to the unit card ie each trooper can choose to throw one. Or is it more like adding in a heavy weapon trooper ie a single model throws the grenade a la 40k?
I'm leaning towards the first interpretation but my searching of the RRD didnt turn up anything concrete.
