What about when a crew member NEEDS both a spyglass and a range-finder more than they need 3 ammo types or 3 repair tools, or perhaps they run a tag team strategy swapping out to use defensive flight tools such as drogue chute and impact bumpers? That top right gun on the front of a pyra can easily be manned by a crew member with a pipewrench, 1 choice of ammo, and nothing else. Absolutely viable, and don't deny it.
copilot is best tactic
