Before I begin, I've searched everywhere and I have no idea what EA based the MEC FAV off of because I can't find a real life picture of it anywhere. If by some chance that I'm not correct in asuming that EA just made it up (like the Z-10 which is actually a A-129 Mangusta *cough cough*), but I'm almost certain that the FAV doesn't exist.
The Fennek is a German scout vehical currently in use which fills the role of a light recon vehical. Although EA displayed the MEC as basically a Russian military clone, PR has been displaying them as a wealthy confederation that uses a combination of new equipment and Bundeswehr overflow, so it stands to reason the Fennek could be used.
So down to business, it has 3 crewmembers: A driver, Gunner, and somebody to operate telescopic camera. It can be equipped the a HK GMG (automatic grenade launcher), a .50 cal HMG, a dutch company is placing stinger missiles on it, and Spike ATGMs. Since the Spike is made by Israel, I find it hard to believe that the MEC would get their hands on one, so a Milan or Kornet ATGM would work better.
Since the UAZ is rather outdated the Fennek could serve as a replacement since a small portion of them are used as Combat Engineering vehicals.
And now for the pretty pictures:




Oh sorry, wrong Fennec.
