I'm learning.
Some birds are key for scenarioos, which are awesome. The PBY is one. In-game it is toast (with peanut butter and jelly) though in a scenario it could be a real enhancement. I would guess strictly early-war, Pacific theater. Maybe first launch pits PBY screen versus a BARCAP to find the CV. Once found second launch is of divebombers, etc to sink it.
I'd add somewhere on the list, a bit down though.
