As one who served, albeit short and a long time ago, I have seen them at close quarters. I also have two nephews who are also serve.
I have great respect for them at all levels. The old 'lions led by donkeys' is no longer true of the British military, that is now British Industry.
Of all of them, the marines, especially the SBS, are the top of the elite.
What I have said will not be popular and I expect large numbers of TDs. I could not give a toss, I will say as I know and not bow to popularity.
