Honour.

A couple poems have always gotten to me about the lot and courage of a Soldier. One is by Rupert Brooke, and the other Alfred, Lord Tennyson.

Particularly, in "the Charge of the Light Brigade" the following lines:

Their's not to make reply,
Their's not to reason why,
Their's but to do and die:

They don't question so that we might. Strong stuff, that.
