The last word on the third visible line is either "value" or possibly "blue".
The nomenclature gives me a hunch that it will in some way cause the main battery to interact with the antisquadron armament. I'm not sure how though. Maybe allow you forego an attack to attack one squadron with your main battery dice instead of antisquadron? I can't see it allowing you to outright swap the values because ISD's and MC80's exist, but for one shot? Not inconceivable. Would make it a huge threat to those escorted Keystone squadrons like Intel, Rhymer, and Relay.
