The Polish Army is active on numerous channels, using both analog voice and digital modes. Most callsigns take form of a word followed by a 2-digit number. In 2G ALE, those callsigns are usually abbreviated down to 3 characters, typically using the first 2 letters of the word and the last digit of the number (e.g. from OSINIEC05 to OS5).
The voice networks exchange 5-letter and 5-digit group messages known as telegrams.
The digital networks exchange email messages. The modes used are 2G ALE (MIL-STD-188-141A) and MIL-STD-188-110, together with the STANAG 5066 protocol.
