[MRCA] WWI Signal Corps Film

[Al Klase]

Ray,

While were on the subject:


 From The Radio Technology Museum - WWII Tactical Communications Display

Signal Corps - Branch Insignia (United States Army)" T-shirt by ...

The insignia represents the flags and torch used for Civil War era 
signaling.
Please Note:  Those are not semaphore flags.  They are wig-wag flags, 
used one at a time to send Morse code or Army equivalent.
One chooses the flag that offers the best contrast against the background.

Ray's right about the telegraph.

End lesson of the day,
Al
