Life... it wasn't that dire. He hadn't committed the gravest of offenses, such as treason, desertion, or disobedience to a superior's orders.
Neglect of duty, dereliction of duty, that was the most serious of his charges.
And in fact, what happened afterward was not far off from his own judgement.
He was stripped of his military post, demoted to the rank of captain, and relegated to a civilian department. Then, six months later, he was reassigned to a new unit, serving as a battalion commander in a garrison division in the Green Valley Region, dealing daily with the Aberrant Beasts that still lingered in the southern Green Valley.
His competence was certainly there, otherwise, he couldn't have been promoted; after making a serious mistake and taking a major hit, one often grows. Besides, merely serving as a battalion commander in a garrison, his abilities were definitely up to the mark.
