(Answered) Range Master SPA & C3

[SC_Dave]

How does the range master SPA interact with C3, is the "C3 range" used in to-hit calculations or the actual range bracket with reference to the SPA?

For example: If a firing unit with the range master (medium range) SPA was at long range from a target unit, but due to the existence of a C3 network the target was to be considered at medium range. Would the to-hit range modifier be +0 (due to the benefits of C3 combined with range master) or +2 (because the target is considered at medium range due to C3, but is not within the range master's true bracket of expertise)?

C3 determines the range bracket, Range Master affects the to-hit modifier of the range bracket. Range Master does nothing to determine what the range bracket is.
In your example, C3 makes it medium range. Range Master would then affect the medium range to-hit modifier. So the result with C3 making it medium and Range Master (Medium) would be +0.
We don't need multiple different range brackets at different steps of the process.  :).  Determine the range bracket, figuring out everything that affects determining the range bracket, and that one range bracket result is used.
