The BS Attack effects limit you to five Guided attacks per player turn. Dahshat can take up to three REMs with BS Attack (Guided) and Shasvastii can theoretically throw all of their SWC into 4 Nox with Guided MSR (or three and a T-Drone). When you use a Coordinated Order on a group like that to make multiple simultaneous BS Attacks that benefit from Guided, does the Coordinated Order count as one use of Guided, or does each participating trooper with Guided count against the limit of five Guided attacks? My assumption is that each trooper counts against the limit, but I can see how you could go either way on it.
How many attacks are being performed? A: each Trooper individual performs the skill so each trooper individually performs an attack so you count them individually.
