Warning to Observation Post Kibitzers

From “Combat Lessons” No. 6:

Says a Captain of a Field Artillery Battalion, France: “Well-meaning infantrymen who crowd about the OP to observe the results of the firing or to steal a look through the BC telescope should be warned that they are inviting fire from the enemy. OP’s are high on the priority list of enemy targets. The importance of OP camouflage discipline cannot be overemphasized.”

“OP\’s are high on the priority list of enemy targets.”
