The crime of assault varies from state to state (and under federal law), but is generally defined as intentionally putting another person in reasonable apprehension or fear of an imminent (immediate) harmful or offensive contact. The crime of assault may be committed even if there is no physical contact, as the criminal physical contact constitutes the separate crime of battery.

The crime of assault with a deadly weapon (also known as aggravated assault) occurs when someone uses a deadly weapon (gun, knife, club, tire iron, brass knuckles, etc.) during an assault.

In Wyoming, assault is defined under state law as an unlawful attempt to cause bodily injury to another person, or intentionally causing bodily injury to another person. The state differentiates between simple assault and aggravated assault. Simple assault, which may involve causing reasonable apprehension of bodily harm without physical contact, is typically treated as a misdemeanor. Aggravated assault, on the other hand, is a more serious offense and occurs when a person intentionally causes bodily injury to another with a deadly weapon or attempts to cause serious bodily injury. Aggravated assault is considered a felony in Wyoming. The use of a deadly weapon, such as a firearm, knife, or any object that can cause death or serious bodily harm, elevates the crime to aggravated assault due to the increased potential for significant injury. Wyoming statutes provide specific definitions and penalties for these offenses, and the exact charges and potential sentences can vary based on the circumstances of the incident and the presence of any aggravating factors.
