Do these qualify as a form of wireless communication?
Has anybody ever used them before or had training on how to use them?

Yes we learnt it in the Sea Cadets in the 50's/60's.

As they rely on photonic reflection to be seen you could say they operate at the frequency of light. The inverse of frequency is wavelength so would qualify for wireless.

Note as well that the flags are Naval and not Army.
