Newspaper reports have claimed that many troops were sent into the

communications equipment.

The Single Channel Ground and Airborne Radio System was designed in the 80's:

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.
