I just walked into our Communications Center to update them with our latest manpower assessments for the upcoming 24 hours and our deployment schedule.
The radio crackled and I answered that we were online and listening.
Our platoon leader then announced over the radio the blessing of Sefirat HaOmer.
Every unit in the area responded affirmative over the radio by answering Amen.
