If this RP is continuing forward, I would like to participate.
As a former Infantryman, I would take on an Operator's position.
I see Sniper, medic and demolitionist taken. I could take on a role as either Fire Support Operator (FSO), Forward Air Controller (FAC) or Heavy Weapons Specialist.

[b]FSO[/b] - Calls in indirect fire from Direct Support (DS) Artillery or Supporting vessel orbitting immediately above the Unit's Area of Operations (AO).

[b]FAC[/b] - Helps guide friendly Attack Aircraft onto observable targets conducing Close Air Support (CAS) Operations.

[b]Heavy Weps[/b] - Knowledgeable of friendly and hostile indirect fire weapons to include artillery, mortars and rocket batteries. May carry a Squad Light Machine Gun (LMG) during operations.

Of course, my terminology is all real world stuff. I need to get into more depth on what you all have written. But this does look fun.
