What does SP stand for? How about TFI?

[kingandrew]

There are all these abriviations used but it never says in the descritpions what they mean.

I believe SP stands for Spec Plus. Don't know about TFI.

kingandrew,

Zuluninja is correct: SP stands for "Spec Plus". TFI stands for "Task Force Infidel". The TFI is a Justin Gingrich Ranger design.
Hope this helps.
