For recon, a plane or heli would be more efficient. Hell, even a buggy would be faster, quieter, and more maneuverable.
I really don't see a practical application at all for these tanks. Too weak (190 +/- fps), too slow, too loud, and too vulnerable. Plus, if you don't have a CCTV or similar system hooked up, you would need to be running around behind it, and monitoring the tank would also place you at risk.
