Hello,

I hope you are doing fine, Of course you can join as a garud commando in iaf. For that you have to first join iaf as a ground duty officer i.e admin, logistics, meteorology & technical (ae & am) . After becoming an officer you can volunteer for the garud. As far as maximum age is considered then it's 23 for non commissioned ranks but for officers no info is available but as maximum age allowed for ground duty officers is 26 and ground duty officers are the ones who volunteer for garud so, I think it's 26 years for officers.

I hope you find this information helpful. I wish you all the best for your future.

Good Luck
