Is this intended? because it's absolutely brutal for satchel charges to not give a grenade warning when they one shot squads and vehicles. Your reaction window is only 1.5 seconds or worse when you consider the time it takes for any unit to start moving and get out of the blast radius+latency, and if doesn't happen on your screen, there's nothing you can really do besides having 1.5 second interval of awareness on the status of every unit which I feel is a bit extreme skill floor for not having units 1 shot, at least beyond 1v1's.
