This tough looking bulldog of a man began his career in the British Army prior to the First World War.  Having survived the meatgrinder that claimed millions of his fellows, and the subsequent downsizing of the Army in the interwar years, he has attained the coveted rank of Colonel.

How and why he got there with such queer ideas is beyond most other officers, and Colonel Nelson is looked on as something of an oddity by his peers.  Nelson is far from a "properly minded" officer, and his bluntness has won him no favors.  This leads many to speculate that he survives by being right (even when being right is highly inconvenient for the powers that be) and having friends in high places.
