How long should I be defered ? I broke my ankle 4 weeks ago and am due to start training on the 8th of October, do you think a year federal is fair ?

Hello, I had passed everything for the army, I got all the way through to the start date point, then I broke my ankle.. The doctor said it will be healed within 6-8 weeks, why have the army defered me from the army for 1 year, I could understand If it was a major brake but it is extremely minor ...
