A little something Cannonshop asked for.
I know it doesn't have the most offensive firepower by Battletech standards and unfortunately there's no MML options for the stealth systems requested but if I did the math right for it's ATACs it can coordinate with 8 Destroyers, the Fighter Wings of said Destroyers, and it's own Fighters. So good luck getting close enough to hurt it in such a scenario.
Catch it by itself, well it is 4/6 with good durability. I can be convinced to bring that down to 3/5 and put in a few more guns if so desired.
