Prussian Army, Second Armored Group, Advance Command Headquarters.
Calling it an Advance Command Headquarters means that the command unit was still in motion, not deployed yet. In such a state, although the command vehicle could receive telegrams, it absolutely could not send any out—the reason was simple: too much shaking. A single jolt could add an extra character to the message, and another shake would add yet another.
When a telegram was sent, the message was transmitted instantly upon pressing down.
Of course, even while in motion, the headquarters could still communicate with all divisions via radio.
The high-power radios carried on the communication vehicles could, if necessary, broadcast at full strength. The messages could potentially be heard as far as Plowsonia.
Thanks to the radio, General Von Maqi was still able to keep abreast of the conditions of his subordinate troops, and occasionally, he could even listen to the battle situations reported by pilots in the air.
