a. Unit
Sig Plt, 26th Bn, 103rd Regt was a telephone signal communication unit with the primary mission of laying telephone wires, repairing telephones and maintaining lines of communications. This unit devised a method of its own in using signal flags to aid in laying and splicing wires.
b. Description of Flags:
Red and white flags, each measuring 30cm X 20cm, were the only two types of flags used in this signal platoon.
c. Use of Flags:
The purpose of these flags was to communicate with other linemen on the job at a reasonable distance (50m to 100m). Flags were sometimes used up to a distance of 2,000m but only when lines were being laid (or repaired) in mountainous and hilly terrain (sic) providing sufficient visibility.
When the white flag was waved by a lineman, it signalled the lineman on the other and to slacken the line (wire); (Red flag: to pull line). This is done until the flag waving lineman raises his flag to a full stop over his head and holds it for a second or so before bringing it down. In this system, linemen worked in pairs.
A slow waving white flag signalled the linemen on the other and to give a steady slack; a slow waving red flag, a steady pull. A fast side to side wave meant a need of plenty of slack or pull until the motion slowed down. If the signaller is located between two groups of linemen, he faces the group he wants, as the case may be, to pull the line and the other group would automatically slack the line unless they in turn receive the signal of white flag moved up and down which means not to respond to signal given to the other end.
d. Use of Flags at Night:
Work was never done at nights so flag system was never used after dark. Other signals with these red and white flags were devised by linemen whenever warranted.
This signal platoon was not engaged in combat and did not conduct activities in combat areas.
e. Other Equipment:
Field telephones were used beside flag signals.
f. Standardization of System:
PW was very sure that the flag signaling system was not standardized.
g. “Rope of White Flags”:
Expression unknown.
h. Personnel Handling Flags:
Platoon leader waves the flag. Flag waving, however, does not indicate that a commander or a command post is located in the immediate vicinity.
i. Deception:
Flags were never used to deceive or confuse the enemy.
For the Commanding Officer:
ROBINSON
