[member="Iris Drathrul"] Maybe you could consider joining the SJ; I'm sure that's what [member="Thurion Heavenshield"], [member="Arisa Yune"] and everyone else in the SJ would want.
[member="Mishka Larraq"] To be fair, these RE PCs' coverage of the Citadel is limited; their perspective has been equally limited. Most of the RE PCs in the Citadel chose their landing zones to be as close to the SJ PCs on the ground as possible. I can't blame them IC for choosing to make their insertion as close as possible to the objective while their respective landing zones are hot. As far as I can tell, however, they did acknowledge they were taking thousands (that's in page 2; it may even be five-digit by now) in casualties. But yes, friendly fire is still a thing.
[member="Catherine Soja"] Given the above, just use some repeaters (railgun, blasters, either will do the job just fine).
