Drones for the Project and for Survivors.

My personal favorite for recon is Flir's day/night Black Hornet which is man portable (168mm long and 33 grams) but also has vehicle mounted launchers available.

The Black Hornet is rather recent, I think being first deployed in 2012. Something that would more likely be in the Project would be the AeroVironment RQ-11 Raven

While it doesn't fit in the palm of your hand, it is still man-portable. Plus it is large enough and has endurance enough to hold a radio relay to extend communications range for a team.
