Run and Gun contains two new missile launcher weapons: the Onotari Arms Ballista MML and the Mitsubishi Yakusoku MRL.
Both are listed as having Accuracy "Missile". This is wrong, because Missiles (and Rockets) don't actually have Accuracy scores. Missile launchers are supposed to get their damage ratings from the missile, but are supposed to have their own Accuracy score.
For comparison, the core book launchers have Accuracy scores of 5, for the Aztechnology Striker; and 4 (6), for the Onotari Interceptor with integrated smartlink.
The available errata for Run and Gun doesn't address this question.
I would prefer a cited official answer if any has been published outside of the errata document. Second best would be a semi-official answer from whoever wrote that part of the book (with citation). Third best would be an argument-from-fluff, or prior edition weapon stats, as to what the Accuracy scores "should" be for these weapons.
