The act of deserting or forsaking; abandonment of a service, a cause, a party, a friend, or any post of duty; the quitting of one's duties willfully and without right; esp., an absconding from military or naval service.
The state of being forsaken; desolation; as, the king in his desertion.
Marriage is good enough for the lower classes: they have facilities for desertion that are denied to us. George Bernard Shaw
Desertion is the army's dirty little secret. Since the beginning of the Iraq war, more than 20,000 American soldiers have given up the fight. Most of them disappear while at home on leave, fading into a network of family and friends, and the army does not typically chase them down. Wil S. Hylton
