So what does a soldier do on a base when not marching, shooting guns, and polishing painting stuff anfd how come theyre not called out straight away in a civil emergency.
The likes of the teeth arms (infantry etc) will train. They spend a lot of time training for their role. There will also be a readiness cycle for a lot of the units who will have to rotate a duty of being on standby as the lead unit to be deployed anywhere as reqired by the govt. As said, a load are still in Afghanistan, so there are those preparing to go, those there and those just back.
The Corps (Royal Engineers, REME, Sigs etc) and most of the RAF do their job on a daily basis. All that equipment gets used in support of those training tasks and other ‘real’ jobs so it neds maintaining and looking after just the same as it does when being used in anger. Plus bomb disposal, search and rescue (for now), aircraft crash recovery, training for prison officer strikes etc etc.
As for being called out earlier – the civil authorities must exhaust mutual aid, the private sector and other agencies before calling for the forces. The military and the civil agencies are totally distinct for lots of reasons. There is work under way to improve the links, but the military are not trained too much in natural disaster recovery or any of the other 1000 tasks people think you can put untrained people in to when it is an emergency.
It is, of course, more complex than this, but you get the idea.
Just a point for a few of the more ignorant posters – it is often better to keep your mouth shut and appear stupid than open it and remove all doubt.
