Multi-Warhead Missile and Critical Hits

Acknowledge, this rule is confusing ...
Agreed, every time I said "according to 2017 beta" there was a discussion in beta, but the rules are still not clarified.

I believe Mongoose is content to leave a little wriggle-room in the rules and let everyone do as they want.
My player will like this; his pilot's Skill 4 + DEX DM +2 = 6. He'll be spinning pirouettes around missile and laser attacks.
Absolutely, as he should, only limited by available Thrust.

Now introduce him to Aid Gunners, and let him give a DM+2 or even +3 on all attack rolls that round.
