This really should go in the "Military Matters" forum, but I'm sure someone will move it if it's really an issue.

The items over the cockpit windows and in front of the nose gear are wire cutters. Standard design, look at any Kiowa Warrior to see the same ones. Most Hueys have them too.
It's been a while since I've been up-close to a french, so I can't say for sure, but the mounts on top of the fuse look like satellite receivers, so possibly both a TACSAT hookup and a GPS receiver.
