Oh yes, I don't believe the Pave Hawk normally uses the minigun (although the Blackhawk does sometimes), and MEDEVAC helicopters (it's in the title) have big crosses on them and are not normally armed.
And in the end for a MEDEVAC, you'd think they'd use the UH-60Q MEDEVAC, and not an MH-60G or HH-60G Pave Hawk. But there are so many variations and off-type usage, you never know.
