Ok answered some other questions regarding re-enlisting on the RAC thrad not realising this problem. Your best bet before you see the Recruiter regarding the Special Enlistment forms at the ACIO you need to get these sorted first as you couldnt join with outstanding offences anyway. Once you have been to court or these charges are quashed the recruiter can assess things. If you do get convicted things will start getting bleak but the Recruiter will need all the details to work it out from RI's. If you arent convicted and no charges are brought against you dont need to say anything.
Keep your fists to yourself in the mean time.
