No mention of "UNIFORM" or "X-RAY" units but I have defiantly heard them. Most of the time you hear "CHARLIE and MIKE" units, but I have heard most of the other ones at least once or twice. Most EPD operations are during normal daytime business hours both weekends and weekdays, and it is not uncommon at all to hear during evening and night hours.
