Ex-serviceman used in a sentence

Ex-serviceman in a sentence as a noun

I can see how a veteran or ex-serviceman could always be very handy in a natural disaster, but that would be because they are able to lead, to follow orders, have plenty of practical skills and are trained to be self-sufficient. But the actual combat training or experience - nevermind the weapons - is not necessarily the most important thing to have when you are hit by a flood or a earthquake or a tsunami.
