Gonna be a late-poster here and stick in my two cents as a former military helicopter pilot, security company dispatcher, and public safety officer. If you are planning to communicate within your own group, SOPs with 'pro-words' (i.e. shortcuts which mean various standard reports or actions) will work - as long as everyone understands the SOP and the pro-words. Communications with outside entities by radio will always work best using plain language. The most frequent problem I have encountered with inter-agency communications is identifying the sender of the message and understanding the message. Communications should be short, to the point, and, especially if using a radio system that has a repeater in the link, the sender should pause long enough, after keying the microphone, to ensure the repeater has a chance to start transmitting. Otherwise, significant parts of the transmission can be unintelligible.
