The top commanders stay to the end, and the radio platoon stays with them; without a powerful radio transmitter, and the cryptographic paraphernalia that goes with it, a general is not a general, a division is not a division. Finally they go off the air, and begin breaking the transmitter down into the smallest pieces they can, which unfortunately are not all that small; a divisional radio transmitter is a powerful beast, made for lighting up the ionosphere. It has an electrical generator, transformers, and other components that cannot be made light. The men of the radio platoon, who would find it difficult to move even the weight of their own skeletons over the mountains and across the surging rivers, will carry the additional burdens of engine blocks, fuel tanks, and transformers.
