How much notice would my husband get before he deploys?

My husband is training in the army to be a cannon crew member (artilery). He is probably going to finish training and school in January of next year. Once he is sent to his duty station, how much time's notice would we get before he gets deployed? I've read that they should give us at least 4 months, but some people say they got only 24 hours. Whats the true amount of notice we should get?How much notice would my husband get before he deploys?
As a cannon crewmember, he will usually know several months in advance before he deploys. The ones who only get 24 hours notice are usually people like Special Forces, Navy SEALS, and other people in Special Operations.How much notice would my husband get before he deploys?
anywhere from 18 hours( been there, done that) to several months.





he will not know until he reports to his first duty station when that unit is scheduled to deploy.





he could literally show up to check in and be told to not bother unpacking,they are leaving in a week.. or the next day.
i got almost a yr in advance but it could be shorter
it depends on where he's going and for what. he could get that much notice, but he might not.
