The Special Air Service are the worlds most elite regiment. This series of Hubs includes a history of the regiment, what they do, the tough selection process and their training, as well as how they react in different situations and a break-down of the different types of operations they may face.
I have published the first, general information, hub here with a description to each part of the series. Do you think many people will find it interesting?
There is a lot of interest by different people of all ages for your topic as for this Hub, I would add a video of some sort that relates to your Hub, even if it's a funny one humor is always good to add to our Hubs, let our audience walk away with a smile next to learning. Also, careful on topics in this area since topic of 'personal protective devices' is not popular.
