No one will deny that communications during war time is crucial. Without an established connection troops will be blind, deaf and unmanageable. It was the signalmen who first learn intelligence reports. Signalmen under fire in the fields and trenches adjusted their uninterrupted communication with each division, wherever it was. And if the equipment let them down, reports had to be delivered on foot. During the war, signalmen were engaged, not only in communications, but also navigation and radar.
