According to The UCMJ that Kerry lied about finishing his obligated service is an offence.
883. ART. 83. FRAUDULENT ENLISTMENT, APPOINTMENT, OR SEPARATION
Any person who--
(1) procures his own enlistment or appointment in the armed forces by knowingly false representation or deliberate concealment as to his qualifications for the enlistment or appointment and receives pay or allowances thereunder; or
(2) procures his own separation from the armed forces by knowingly false representation or deliberate concealment as to his eligibility for that separation;
Clearly according to the records he has allowed on his website he was not eligible for separation having only served three years, eight months, and 18 days out of the six years and six months he was supposed to have served.
And if he was released early for whatever reasons, where is the order from the Department of the Navy releasing him from his obligation?
Well, Kerry did not need to lie about it. The Navy would have known when his obligated service would have been served. He asked for an early discharge and the Navy said, "No."
As I noted to kabar in Post 122:
If Kerry had the gall to ask for a ticket home after only 4 months of duty in his Vietnam combat tour because of three Band-Aid Purple Hearts........
If Kerry had the gall to ask for an early release of active duty on 21 November 1969 ......
What makes you think that Kerry would not have had the gall to ask for an early discharge on 3 JAN 1970 before his obligated service was completed?
