Fort Hood is ramping up its gun-registration policy in the wake of last month's deadly mass shooting.
Soldiers and their families living on the Army post and anyone staying there temporarily must register any personal weapon that's kept there.
Now, the policy also applies to soldiers living off post and civilian hunters if they plan to use a gun at Fort Hood.
Those who enter the post must tell guards if they have a weapon with them.
Post officials say they will increase enforcement and inspection, and those who don't comply face penalties.
Officials say the changes were made after the Nov. 5 shooting on the post that left 13 dead and dozens more wounded. An Army psychiatrist who lived off post, Maj. Nidal Hasan, has been charged in the case.
