Men who adopt the profession of arms submit to their own free will
to a law of perpetual constraint of their own accord.
They resist their right to live where they choose,
to say what they think, to dress as they like.
It needs but an order to settle from their family and dislocate their normal lives.
In the world of command they must rise, march, run,
endure bad weather, go without sleep or food,
be isolated in some distant post, work until they drop.
If they drop in their tracks, if their ashes are scattered in the four winds,
that is all part and parcel of their job.
-Charles de Gaulle, French General and Statesman.
