Can I back off from the army once in it?

Thank you for your question Marian,

There will be a window throughout training called a DOAR window in which you can put your notice in to leave. You can leave up until your 18th birthday, after that you will owe a minimum term of 4 years, terminating your contract after 3 years then undergoing some leave and resettlement that will take you up to your 4th year. After the minimum time served, you can get out at any point but the same 12 months notice will apply.

Hope this answers your question
