You are Wrong.
Perhaps misinformed or misguided, but still wrong.
It is an individual right of the citizen to keep and bear arms.
District of Columbia v. Heller in 2008. The case centered on Dick Heller, a licensed special police office in Washington, D.C., who challenged the nation's capital's handgun ban. For the first time, the Supreme Court ruled that despite state laws, individuals who were not part of a state militia did have the right to bear arms. As part of its ruling, the court wrote, "The Second Amendment protects an individual right to possess a firearm unconnected with service in a militia, and to use that arm for traditionally lawful purposes, such as self-defense within the home."
The court would rule on the issue again two years later as part of McDonald v. City of Chicago, which challenged the city's ban on private handgun ownership. In a similar 5-to-4 ruling, the court affirmed its decision in the Heller case, saying the Second Amendment "applies equally to the federal government and the states."
The Supreme Court again ruled on a right-to-bear-arms case in 2016, Caetano v. Massachusetts. The case involved a woman who was in possession of a stun gun for self-defense against an abusive ex-boyfriend. Because stun guns were illegal under Massachusetts law, the woman was arrested and convicted for possessing the weapon. The case made its way to the Supreme Court, which ruled that stun guns and, indeed "all instruments that constitute bearable arms," are protected under the Second Amendment.
