Regarding command and control of units during battle through trumpets, drums and similar methods of audible communication, a question I've often wondered is if there are any instances in the historical record of: 1. Employing a form of COMINT by 'intercepting' (hearing) the enemy communications, and using that information to alter your forces actions? Were there any attempts to keep the signals secret, or change them to avoid this? 2. Employing a form of military deception by issuing false or confusing signals mimicking the enemy signals (sounding the enemy's retreat or halt signals for example) 3. If &quot;Jamming&quot; was possible by attempting to drown out the horns\/drums by making even more noise; And lastly 4: If there was any targeting of enemy C2 by deliberately seeking to use ranged weapons surgically against signallers? Thanks so much for answering the last question too, hopefully I'll get around to that post card one day!
