[@Silverwind Blade] Okay rephrasing with more details: Since the Major is Ranger 1, which of the other flight members are Ranger 2 to Ranger 5.

Ranger 2 - Massasauga (since you bought it up :P)
Ranger 3 - Pilatus
Ranger 4 - Slypheed
Ranger 5 - Foster

Assume the order to be the same for every mission in the future, just to save admin time and to make it easier for us all to remember.
