I believe the military should be entirely voluntary without a draft with the exception of a war on American soil where ALL men of age are required to obey the call if summoned by our Government. Women would remain voluntary.

As for this guy...He joined and accepted the responsibility. He should have to re-pay the government with penalties for any and all benefits he received which would include any training cost, housing, food, transportation and any financial compensation he received during his enlistment. He should then be charged with desertion in a military court.
