According to an archived Russian web page (purportedly written by the Russian Strategic Rocket Forces), UVB-76 is used to transfer orders to military personnel, along with the time at which they should be executed. Sample orders are given on this page, which match the format of messages transmitted by the station in the past: 45359 ½ 3749 6335 79992 f 9923 7768 7117 5770 28138 77560151 05515597 76785508 6121 2637 0931 "Words for the radio messages and code tables are selected mainly from the scientific terms of chemistry (Brohman), Geology (ganomatit), philology (Izafat), geography (Bong), Zoology (kariama), history (Scythian), cooking (drying), sports (krolist) and others, as well as rare Russian words (glashatel)."
The page continues to list all 23 transmissions that have been made from the station in the past, showing that UVB-76 may be more active than believed.
