While the RP focuses on the perspective of the Panthers' pilots, there's room for logistical personnel within the company. I'm not sure if any of you are familiar with Gundam's 08th MS Team installment, but the team operates alongside a [url=http://gundam.wikia.com/wiki/Type_74_Hover_Truck]support truck[/url] that gives additional support in the form of sonar and comm suites. In the original SNES Front Mission game, your team has a supply truck for mid-operation rearms and repairs. So a position like that is entirely feasible, but best left to a maximum of one or two players per vehicle. 
Assets like air support and transports are intended to be restricted to NPCs, since their use is not guaranteed for each and every operation, and I cannot promise a player who's solely dedicated to one of those will have much to do when they're not in use.

I'm not sure how to handle non-Panther characters, since the organization's FRAME team is the focus of the RP. Cradle Dynamics is a client of the Panthers at the immediate start of the RP, though there's no guarantee it will stay that way over time. I suppose you could tag along with the Panthers as an arms dealer of sorts, scavenging from downed FRAMEs after operations and helping the crews work on the Panthers' machines? Different shops will carry different assortments of FRAME equipment and we'll be doing a bit of travel. If you're still interested when the OOC goes up, you can run some more ideas by me. There's no hard player limit, but do note that Panther characters take precedence, being the focus of the RP.

I'll try to be specific here; the pace of combat is intended to be slower and more deliberate than Armored Core or Gundam, but faster than Battletech/Mechwarrior. Imagine an infantry fireteam sweeping through the hallways of a building. Now imagine FRAMEs sweeping through urban streets. FRAME combat has the potential to be faster, as evident by the 'skate' ability they have, but you won't see many pilots zipping around everywhere in the middle of a firefight (unless they're dashing to cover or making a hit-and-run attack, perhaps). 

Here are a couple more cinematics to take reference from. Combat in the RP will probably be more deliberate and won't feature as much skating than they depict, but otherwise, they're pretty similar. FRAMEs are pretty mobile and are known for hitting quickly and hard.

That said, I'm very flexible, so if you guys have common preferences, I'm willing to cater to them.
