It is commonly referred to as illegal firearms' possession. This offense is outlined in the Uniform Code of Military Justice (CMJ) and is punishable by up to 10 years in prison. There are two main types of Firearm Offenses — Knowing Possession Defined (revised 2014): knowing possession with intent to use the firearm unlawfully, and knowing possession with intent to cause another person to use the firearm unlawfully. Both of these offenses are considered felonies and carry severe penalties. In addition, under the revised 2014 version of the CMJ, those convicted of knowing possession of firearms are subject to mandatory minimum sentences.
