With his pilot ability, Dutch is the supportive Y-Wing wingman every Rebel pilot wants next to them. He can be outfitted in a number of ways, with any torpedo, Guidance Chips and Extra Munitions you can be sure the first engagement with the enemy will be a hurtful one.
A Targeting Astromech allows for the red manoeuvres to keep Dutch in the fight by granting him a target lock to perhaps get off the second salvo of munitions whilst spreading the love to nearby squad members.
Dorsal Turret is worth looking at to cut down the costs of the usual turret options, and the newer Vectored Thrusters could be a consideration for Dutch as well.
Of course, this is only a tiny few options available, he can be equipped with R2-D6 in order to unlock the Elite Pilot Skill upgrade slot.
