I've been training leadership skill lately not only so I can be a good sqaud / wing booster when in a position of command but also so I can fit out a nice Vulture Command Ship. My requirements for the warfare links are done and I can now fly my latest addition to the fleet, Rearguard:
On paper it doesn't look too intimidating: anemic DPS, decent passive tank due to resistances, rather unremarkable. But let's see what it does to the
average ship of the line battleship. Here is a Megathron sniper's stats before and after applying the squad commander from the Rearguard:
From my skills, there are more shield and armour hitpoints, better agility, and longer targeting range. From the Rearguard's warfare link modules there are better resistances and lower signature radius. The end result is a ship that can absorb much more damage and get out slightly faster. With a Siege Warfare Mindlink implant I could get even better resistances and more shield points for ships underneath my command level.
A shield tanking ship like a Rokh benefits even more as its natural resistances are augmented even more by the Command ship.
