Here's my question to you, is the class on FBCB2, or Blue Force Tracking technology??
FBCB2 is a type of Blue Force Tracking, it's like saying MaxxPro is a Type of MRAP, is the class on MRAP's in general or is the class on specifically MAXXPRO?
If the class is on BFT Technology just use Wiki to learn the concepts and explain them to whoever you are teaching along with more informative examples from that website you posted that loaded for me -> http://en.wikipedia.org/wiki/Blue_Force_Tracking
Now, if your class is supposed to be on FBCB2:
If your near a major base there is a class your S3 can send you to for FBCB2, it's like 40-80 hours and it will 'cert' you on teaching everything but administration, there's a seperate class for that.
If your unable to attend that class or talk to someone who has, I'd suggest you explain to capabilities for the FBCB2 if they are on that site you posted. Explain the concept of why we use it and why it was developed and what platforms it is used on and for what unit size. BDE and Below, maintenence, how to destroy in case of emergency, ect.
Other then that, I wouldn't expect anyone that hasn't put hands on one to teach everyone else how to use it, that's just ridiculous, but not uncommon.
It's really not difficult to learn, anyone computer savvy can learn the functions in an hour.
