Newspaper reports have claimed that many troops were sent into the field with old equipment - including in particular 10+-year-old communications equipment.
The Single Channel Ground and Airborne Radio System was designed in the 80's: http://www.fas.org/man/dod-101/sys/land/sincgars.htm I don't know the hop frequency, but it's probably smaller than modern standards (could possibly be followed with real-time tracking), it probably uses a manually-entered seed to generate a hop sequence, the PRNG that stretches the seed is probably not secure any more, and the input space is probably searchable by now in a reasonable amount of time. Further, once broken with some expensive hardware (maybe a custom-designed SIGINT SDR), they could program much cheaper units to follow the sequence until the Israelis re-keyed. Just my total guess. -- "On the Internet noone knows you're a dog - except Bruce Schneier."
