Hey Recruit,
Unfortunately the issue is not the time to fit into trainings but as a conflict of interest. The 29th Infantry Division also has a presence in Arma 3, so you can imagine that if you remain in the 506th, it is possible you could be fighting the 29th in inter-unit scrims. It is for this reason that your application has been denied.
Thanks,
J. Sarsfield
