I assume you mean 25 MI Coy (V) - have you followed the links from the website to the TA site and checked out the stickies? Once you have done that please come back with specific questions. Do you want to join as an officer or soldier? What is your age, background (student, UOTC, already in the TA, ex-Regular), educational qualifications etc.
There is only so much sarcasm my fellow Intelligencers can be bothered to waste on a question so broad!
