ECM Suites allow mechs to use Ghost Targets under Advanced rules, and we have one protomech (Roc 4) that canonically has an ECM suite.
Normally, this would require a piloting roll to succeed, but protos don't have a pilot score.
So, my question is whether or not Protomechs apply their Gunnery score to this roll, or if there is some other value they should substitute.
