A slight digression for all those who still serve and whose service I value and respect, and whom I would like to see stay safe......
I am recently back from a far away overseas holiday (matters not where) and spent an evening at a posh shopping mall, with many eateries, a few miles away from a large (not UK or US) military base.
Scoffing our scram, myself and my wife played "spot the off-duty military dude/dude-ess". It is INCREDIBLY easy to pick you guys/girls out in crowd.
Your haircuts.
Your physique.
The way you carry yourselves.
And, most of all, you are always in groups of similar types.
I'm not suggesting much can be done, or that you hide (don't let terror win and all that)
I'm merely pointing out an awareness issue...civvy clothes rarely hides who a serviceman is.
Be safe one and all.
