There are some notable exceptions to the above.
1. When passing numbers a decimal point is transmitted as "DECIMAL." This is important during the transmission of radio telephony (r/t) frequencies, mainly because DECIMAL is trisyllabic and should therefore be easier to pick out on a garbled or interfered frequency. For example, "DELTA TWO THIS IS DELTA ONE CONTACT CONTROL ON ONE TWO FIFE DECIMAL SEVEN FIFE." (Don't ask why, but transmissions are by convention written in capitals.)
2. When passing a bearing and range the range should be given in whole numbers (eg FIFTY SIX as opposed to FIFE SIX). This is to prevent the receiver from hearing a long string of confusing numbers. So, for example, if D1 wishes to tell D2 about a contact due east at a range of 145 miles from D2, the transmission would be "DELTA TWO THIS IS DELTA ONE CONTACT YANKEE YANKEE ZERO NINER ZERO ONE-HUNDRED-AND-FORTY-FIFE", as opposed to the confusing "ZERO NINER ZERO ONE FOUR FIFE." (YANKEE YANKEE = from your current position)
3. Common abbreviations such as ESM (electronic support measures), EW (electronic warfare), r/t (radio telephony) and RAF (Royal Air Force) are passed in usual format for brevity - ie, "DELTA TWO THIS IS DELTA ONE R A F ACTIVITY IN HIGH E W REGION DETECTED CONTACT R A F ON USUAL R T FREQUENCY" as opposed to the unneccesarily time-consuming, "DELTA TWO THIS IS DELTA ONE ROMEO ALFA FOXTROT ACTIVITY IN HIGH ECHO WHISKY REGION DETECTED CONTACT ROMEO ALFA FOXTROT ON USUAL ROMEO TANGO FREQUENCY."
