​Illinois Armed Violence 720 ILCS 5/33A Explained​
posted on 8/18/26

It is important to understand that the state of Illinois punishes individuals who have committed armed violence. The offense is governed primarily under 720 ILCS 5/33A, Article 33A of the Illinois Criminal Code. As such, it is essential to know that armed violence is not simply a charge that alleges you possessed a weapon. Instead, the statute generally connects an alleged weapon possession or discharge during the commission of another felony.

Being charged with Armed Violence in Illinois can expose you to substantial criminal penalties if you are convicted. The extent of your sentence will depend on the following:​

  • The precise underlying felony being committed
  • The type of weapon that was involved in the commission of that felony
  • Whether the firearm was discharged during the felony act

If you have been arrested and charged with armed violence in Illinois, you should immediately seek the assistance and guidance of an experienced attorney. Do not assume that because you did not fire your weapon that this charge will not apply to you. For example, Section 33A-2(a) addresses being armed with a dangerous weapon while committing a qualifying felony, with separate provisions for the actual discharge of your firearm.​

Understanding Armed Violence Under Illinois Law

A person commits armed violence when they are armed with a qualifying dangerous weapon while they are also committing a felony.​

Additionally, the statute separately addresses situations where someone personally discharges certain firearms while committing a felony offense. Further, there is a provision that applies when the firearm is discharged in a proximity that causes great bodily harm, permanent disability, permanent disfigurement, or death.​

When an armed violence case is tried, there are often two important components:​

  1. The underlying felony
  2. The alleged possession or use of a qualifying weapon in connection with the felonious act

What Are Qualifying Weapons?

For the purposes of Article 33A, dangerous weapons are divided into three categories.​

Category 1

These weapons include handguns, sawed-off shotguns, sawed-off rifles, certain concealable firearms, semiautomatic firearms, and machine guns.​

Category 11

These weapons include certain rifles and shotguns as well as various other weapons like certain stun guns or tasers, knives with blades of at least three inches, daggers, dirks, switchblades, stilettos, axes, hatchets, and other similarly dangerous weapons.​

Category 111

These weapons include bludgeons, blackjacks, slungshots, sandbags, metal knuckles, billys, and similar dangerous weapons.​

Remember, details matter. The classification of the alleged weapon in an armed violence charge can be extremely important to a defendant. This is because the different categories of weapons can result in substantially different sentencing consequences. To ensure that you are able to obtain the most optimal outcome in your armed violence case, you must not wait to speak with an attorney if you have been arrested or are under investigation.​
