Rejoining the army

It used to be you could do it within 90 days, hence the term "90 day wonder". I suspect you are past the point of no return, and too old for a new enlistment. Just my opinion. . . .

Ask your local recruiter. They get paid for stuff like this.

No one knows what country you are referring to Jay. Each country's military has its own set of enlistment rules.

Why ask such a question here when a simple phone call to a military recruiter office should give you the answer?
