What your talking about are the basic actions at a low level which yes, don’t change. Hot, take jacket off. Cold, put jacket on. Sure.
You’re opening was statement that training to prevent cold (and heat) injuries hasn’t changed in 40 years. That is just incorrect.
10 years ago the only ‘training’ around hot and cold injuries was your basic single slide as part of your first aid training. Today we have extensive training materials on DLE and as policy to help us manage these risks properly. All formed off the back of people dying because the training didn’t exist. The training to prevent these types of injuries from happening has come a long way in 10 years, let alone 40.
Now, it’s all almost a complete null and void argument for us, as although there is loads of training and help, it’s all aimed at serving military personnel. Not 13 year old going for a walk when it’s a bit warm or a bit cold. We’re not going to be in -40C arctic weather, nor 40C heat.
For the occasional event, it’s very necessary. Running X-country in Jan when it’s -5C does need some proper planning, and so does running a DofE event when it’s 30C. Both those examples, 10 years ago, would have been planned just based on what the CFAV thought was right at the time. At least now we have a framework to work with to help us guide our decisions. Even if that framework isn’t ideal.
You’re partly correct about the issue kit though. It’s easy to say we need C, Y and Z when we don’t give them out. But there’s ways and means of working around that. And because we don’t issue certain kit, it makes the risk assessment process that more important, as the range of kit that cadets turn up wearing needs to be taken into account.
