Yes, tanks are legal to own in the United States. A demilitarized tank, meaning one whose cannon and weapon systems have been permanently disabled, is treated under federal law much like any other large vehicle, and thousands are in private hands. A tank whose cannon still fires is a different matter: it is classified as a destructive device under the National Firearms Act, requires federal registration and a $200 tax per weapon, and is banned outright in several states. Either way, getting a tank home, insured, and anywhere it can actually move is its own project.
What Federal Law Cares About: The Cannon
Federal law defines a “destructive device” as any weapon that fires a projectile through a barrel with a bore diameter greater than one-half inch, along with bombs, grenades, rockets, mines, and similar explosive devices. A tank’s main cannon clears that half-inch threshold easily.1Office of the Law Revision Counsel. 26 USC 5845 – Definitions
The definition carves out weapons that have been redesigned so they no longer function. A tank whose cannon has been permanently disabled cannot expel a projectile, so it no longer meets the statutory definition of a destructive device. That single distinction is what separates the ordinary civilian tank market from the tiny, heavily regulated world of functional tank cannons.
Buying a Demilitarized Tank
Before the Department of Defense releases surplus military equipment, it assigns a demilitarization code that dictates how thoroughly the item must be disabled. For combat vehicles, that typically means destroying or removing key weapon components so the vehicle cannot be restored to combat capability.2Department of Defense. DoD Manual 4160.28 Volume 2 – Defense Demilitarization Procedures Qualified government employees or defense contractors perform and certify the work before the vehicle leaves DoD custody.
Demilitarized tanks reach civilians through two main channels. Government auction platforms sell surplus U.S. military equipment directly to registered bidders. Specialized dealers import and refurbish foreign military vehicles from allied nations. In both cases, weapons are already disabled before sale, so the buyer receives a vehicle that sits outside the NFA’s destructive device rules.
Prices vary widely. Lighter armored vehicles and older foreign models can sell for under $100,000, while Western main battle tanks can start above $500,000. That is only the sticker price. Transport, storage, and maintenance add substantially to what ownership actually costs.
Owning a Tank With a Working Cannon
A tank whose cannon still fires is a registered destructive device, and owning one legally means working through the National Firearms Act. Every transfer requires ATF approval on Form 4 before the weapon changes hands. The transferee submits fingerprints, photographs, and a $200 transfer tax.3Office of the Law Revision Counsel. 26 USC 5811 – Transfer Tax ATF then runs its own background investigation and denies the application if possession would violate any federal, state, or local law.4Bureau of Alcohol, Tobacco, Firearms and Explosives. Chapter 9 – Transfers of NFA Firearms
Very few functional tank cannons are in private hands. The registered supply is limited, the approval process takes months, and the penalties for getting anything wrong are severe. Possessing an unregistered NFA firearm carries up to ten years in federal prison and a $10,000 fine.5Office of the Law Revision Counsel. 26 USC 5871 – Penalties The weapon itself is subject to seizure and forfeiture.6Office of the Law Revision Counsel. 26 USC 5872 – Forfeitures The prohibited acts statute makes no distinction between innocent mistakes and intentional violations.7GovInfo. 26 USC 5861 – Prohibited Acts Anyone considering ownership needs to verify the weapon is properly registered in the National Firearms Registration and Transfer Record before taking possession.
Ammunition Is Regulated Round by Round
Each explosive or incendiary round containing more than a quarter ounce of explosive material is itself a destructive device.1Office of the Law Revision Counsel. 26 USC 5845 – Definitions Every shell requires its own registration and its own $200 transfer tax.3Office of the Law Revision Counsel. 26 USC 5811 – Transfer Tax A single round of tank ammunition can cost more in tax stamps than the round itself is worth.
Inert or practice ammunition with no explosive filler does not meet the threshold and is not subject to NFA regulation. Owners who actually want to fire their cannon generally use solid practice rounds for that reason.
State and Local Bans Can Override the Federal Path
Federal law offers a pathway to own a registered destructive device, but state law can close it. Several states prohibit civilian ownership of destructive devices regardless of federal registration. Others allow some but ban specific types, and county or municipal ordinances can layer on further restrictions. If state law bans possession, ATF will deny the Form 4 application.4Bureau of Alcohol, Tobacco, Firearms and Explosives. Chapter 9 – Transfers of NFA Firearms
Demilitarized tanks are a different story. Because they no longer qualify as destructive devices, state NFA restrictions generally do not reach them.
Importing a Foreign Tank
Many privately owned tanks are foreign models. Tanks fall under Category VII of the U.S. Munitions List, which covers armored combat ground vehicles.8eCFR. 22 CFR Part 121 – The United States Munitions List Permanent imports of defense articles are regulated by ATF through the U.S. Munitions Import List.9eCFR. 22 CFR Part 120 – Purpose and Definitions
In practice, most buyers go through specialized import dealers. The dealer handles demilitarization certification (often done in the country of origin before export), obtains the import approvals, and ensures the vehicle arrives in compliant condition. Trying to import a military vehicle independently, without a working command of both the ITAR framework and the ATF import process, is a fast way to have the vehicle seized at the port.
Getting a Tank on Public Roads
Owning a demilitarized tank is the easy part. Driving it anywhere legally is much harder. Federal regulations cap gross vehicle weight on Interstate highways at 80,000 pounds.10FHWA. Compilation of Existing State Truck Size and Weight Limit Laws An M60 Patton, one of the more commonly available American tanks, weighs roughly 120,000 pounds. Even lighter armored vehicles routinely exceed single-axle and tandem-axle limits.11eCFR. 23 CFR 658.17 – Weight
Weight is not the only issue. Steel tracks destroy asphalt, so most jurisdictions require rubber track pads before a tracked vehicle operates on paved roads. The tank must also carry basic road-safety equipment: headlights, taillights, turn signals, mirrors, and brake lights. Width is another obstacle, since many tanks exceed the standard legal vehicle width.
Some states have created special registration categories for historic military vehicles that relax certain equipment or weight rules, typically limiting use to parades, exhibitions, and maintenance trips. Where those categories exist, they are the most realistic route to any road use. Without one, most main battle tanks cannot be made street-legal, and owners are limited to private property.
Transport, Storage, and Running Costs
Because most tanks cannot legally drive on public roads, moving one after purchase means hiring a heavy-haul trucking company with a lowboy or RGN trailer. Expect roughly $3.50 to $4.00 per mile for the trailer, with minimum charges on shorter runs. A cross-country haul can easily land between $5,000 and $15,000 depending on distance, route restrictions, and permit requirements.
Oversize and overweight permits are required in every state the transport passes through. Each state charges its own fee and sets its own rules on hours and routes. The trucking company usually handles the paperwork, but the cost passes to the buyer.
Storage catches most buyers off guard. A tank needs firm, level ground that can carry its weight without sinking, and ideally shelter from weather, since tracked vehicles deteriorate quickly when exposed. Running maintenance is another matter entirely. A tank in operating condition burns through fuel, hydraulic fluid, and track components at rates that make classic car ownership look cheap. Parts for foreign vehicles can be hard to source, and some components require custom fabrication.
Registration fees for heavy or historic military vehicles range from under $100 to several hundred dollars annually depending on the state. Insurance is its own puzzle: standard auto policies will not cover a military vehicle, and the specialty insurers who will write a policy price it accordingly.
