The RSA is calling for post-traumatic stress disorder to be referred to as a battle wound to properly reflect what service people go through.
RSA national support services manager Mark Compain said in an article on the RSA website that describing a raft of symptoms as a disorder was "dumbing down" how profound the condition could be.
"The nature of operational service has changed since the 1960s due in part to the way modern conflict is fought in today's operational theatres. Our service men and women go into environments where the enemy cannot be easily identified, where there is no frontline, while still carrying significant weight on their back and around their bodies that their forebears knew," said Compain, a former veteran of five overseas deployments and 21 years in the regular army.
"They can be exposed to a range of environmental risk factors while constantly on guard from threats that hide among the local population and erupt with little warning - like IEDs that can be activated at distance with the flick of a switch - or constantly processing vast amounts of information to prevent illegal activity, on the land or sea or in the air.
"This is what the day-to-day reality of contemporary operations is, and operating for months at a time in this environment without a break can take a toll. This can then be amplified by our people conducting multiple operational tours."
