There are no age or gender restrictions as long as the candidate meets the physical and mental requirements they are guaranteed the opportunity to try out for the ODSTs.
Above was taken from Halo Wiki, so I'd say choose a rank.
And I doubt there is a difference for driving a tank, if you are trained to use a tank, that's what you will be in more than likely.
No offense, just read what I wrote: What RANK do you need, not to become an ODST but to lead an ODST platoon.
If there is no age limit, I would assume no rank limit is required, that's just my opinion.
