If they had no fatalities the had 'Zero Killed' or 0K for short. What do you think? Personally i like this conclusion.

I've never seen the word OK used in any War Diaries or battle reports in WW1 records, as to the use of radio, never heard of them being used on WW1 battle fields, radio was in its infancy, even aircraft used to pass messages by drpping them in weighted tin cans, sometimes heliographs were used to signal aircraft. Most messages were either written & carried by runners, sephamore flags, and telephone lines, were most commonly used, many men won medals for keeping telephone lines working during heavy battles under artillery, and M.G. fire.
