18 U.S.C. § 641 and 10 U.S.C. § 921 (UCMJ Art. 121) cover the theft, embezzlement, conversion, and wrongful taking of government or military property.
These laws can apply when weapons, night vision devices, optics, ammunition, electronics, vehicle parts, or other defense supplies are diverted from military control.
Civilian contractors generally face federal prosecution under Section 641, while service members may also face court-martial charges under Article 121.
What Does 18 U.S.C. § 641 Prohibit?
18 U.S.C. § 641 is the principal federal statute covering theft and conversion of United States property. It applies to anyone who embezzles, steals, purloins, or knowingly converts U.S. property, as well as anyone who sells, conveys, or disposes of it without authority.
The statute reaches more than property already sitting in a federal warehouse. It expressly includes property “made or being made under contract” for the United States.
That language can bring defense contractors, subcontractors, warehouse employees, logistics personnel, and others handling government-owned or government-bound equipment within the scope of a Section 641 investigation.
Section 641 also covers a person who receives, conceals, or retains covered property for personal use or gain while knowing it was stolen, embezzled, or converted. A buyer or intermediary can face exposure even if that person never entered a military installation or personally removed the equipment.
What is Embezzlement or Conversion of Military Property?
Military-property cases do not always involve someone physically stealing an item from an armory. Embezzlement generally involves property lawfully entrusted to a person before it is misappropriated.
Conversion concerns unauthorized control or use of property inconsistent with the government's ownership rights. Examples of potential allegations include:
- Removing gear, such as night vision goggles, from accountable inventory and selling them privately
- Diverting government-purchased optics or electronics before delivery
- Using false inventory entries to conceal missing weapons or equipment
- Keeping military equipment that was issued for official duties and treating it as personal property
- Transferring government-owned parts to another person without authority
- Receiving military equipment while knowing it was unlawfully removed from government control
This makes documentation especially significant in contractor and logistics cases. Purchase orders, hand receipts, property books, shipping records, disposal documents, serial-number records, and contract terms can establish who owned an item and whether a transfer was authorized.
What Does 10 U.S.C. § 921/UCMJ Article 121 Cover?
For people subject to the Uniform Code of Military Justice, Article 121, 10 U.S.C. § 921, covers both larceny and wrongful appropriation.
A person commits larceny by wrongfully taking, obtaining, or withholding property with the intent to permanently deprive the owner of its use or benefit. Wrongful appropriation uses similar conduct but involves an intent to deprive the owner temporarily.
That difference can become central when a service member claims they borrowed, moved, or used equipment without authorization but never intended to keep or sell it permanently.
Under the Manual for Courts-Martial, maximum penalties for military property worth over $1,000 differ significantly based on the service member's intent:
- Larceny (Permanent Intent): Larceny of military property worth more than $1,000—or of any military motor vehicle, aircraft, vessel, firearm, or explosive—carries up to 10 years of confinement, forfeiture of all pay and allowances, and a dishonorable discharge.
- Wrongful Appropriation (Temporary Intent): If the prosecution only establishes an intent to temporarily deprive the government (unauthorized borrowing or temporary use), the maximum confinement drops to 2 years, even for military property valued over $1,000.
What Must Federal Prosecutors Prove Under 18 U.S.C. § 641?
The precise elements depend on the charges. In a typical theft or conversion prosecution, the government generally must establish beyond a reasonable doubt that:
- The property belonged to the United States or a federal department or agency, or was property made or being made under contract for the United States
- The defendant embezzled, stole, purloined, or knowingly converted the property, or sold, conveyed, or disposed of it without authority
- The defendant acted knowingly and with the intent required for the charged form of the offense
- The property exceeded $1,000 in value if prosecutors seek the felony penalty based on value
How Does the $1,000 Threshold Affect a Section 641 Charge?
Section 641 authorizes up to 10 years in federal prison when the statutory felony threshold is met. If the aggregate value of the property across all counts of conviction in a single case does not exceed $1,000, the maximum imprisonment is one year.
The statute defines value as face, par, or market value, or wholesale or retail cost price, whichever is greater.
That definition can produce disputes involving used, damaged, obsolete, surplus, or specialized defense equipment. The price originally paid for a device does not necessarily answer every valuation question.
In a case involving several pieces of equipment, Section 641 expressly permits aggregation across counts of conviction. Multiple lower-value items can place the case above the $1,000 threshold.
Can a Civilian Contractor Be Charged With Theft of Military Property?
Yes. Section 641 is not limited to members of the Armed Forces or federal employees. A civilian contractor can be prosecuted if the property falls within the statute and the person engages in prohibited conduct with the required knowledge and intent.
Contract terms may become central. Defense contracts can:
- Address title,
- Government-furnished property,
- Contractor-acquired property,
- Scrap,
- Excess materials,
- Disposition instructions, and
- When ownership passes.
Investigators may characterize equipment as federal property based on its origin or intended use, while the contract and acquisition records may show a more complex ownership history. For National Guard property, federal ownership also requires careful attention.
Department of Justice guidance states that military property issued by the United States to the National Guard remains U.S. property. In contrast, certain property the Guard purchases with its own funds may instead belong to the state.

Hypothetical Case Study: $3.2 Million in Military Equipment Allegedly Diverted from a Defense Supply Program
A senior logistics manager for a defense subcontractor oversees a warehouse supplying equipment to several U.S. military units.
After a government audit identifies major inventory discrepancies, federal investigators allege that the manager participated in a three-year scheme to divert more than $3.2 million in:
- Thermal weapon sights,
- Night vision devices,
- Infrared laser aiming systems,
- Encrypted radios,
- Ballistic equipment, and
- Aircraft components.
Investigators later recover some of the equipment from commercial resellers and overseas purchasers.
Investigators uncover encrypted messages discussing serial numbers and resale prices, transfers to storage facilities connected to the manager, and inventory adjustments made through the manager's credentials shortly before scheduled audits.
Bank records also show hundreds of thousands of dollars moving through a company owned by the manager's brother.
Prosecutors allege that the company was used to receive proceeds from stolen military property and consider charges under 18 U.S.C. § 641 together with conspiracy and money laundering offenses.
Federal Case Review by Eisner Gorin LLP
Our attorneys obtained the prime contract, subcontracts, government-furnished property records, warehouse access data, inventory audit logs, shipping records, and communications from other employees with access to the same equipment.
The records reveal a substantially different allocation of responsibility than investigators alleged.
Nearly $1.8 million of the equipment had been purchased by the subcontractor and had not yet become U.S. property under the applicable contracts.
Access records place another employee inside the secured storage area when several shipments disappeared.
Forensic analysis also shows that hundreds of inventory changes attributed to the manager were made through a shared terminal after he provided his credentials to several supervisors under the warehouse's existing operating procedures.
Review of the Financial Evidence
The financial evidence requires separate analysis. Payments to the brother's company initially appear to connect the manager to the resale operation.
Still, invoices, tax records, and bank records establish that most of those transfers came from an unrelated equipment-leasing business. The remaining transfers cannot be traced to the sale of the missing military property.
One group of thermal sights, however, presents a serious problem. Messages establish that the manager knew those devices belonged to the United States and authorized their removal for private resale.
Review of the Contract and Title Records
Our criminal defense team uses the contract and title records to challenge the government's $3.2 million theft theory, the access evidence to dispute responsibility for much of the missing inventory, and the financial records to undermine the alleged laundering operation.
The case is ultimately resolved through a plea involving the smaller group of government-owned thermal sights.
By narrowing the case from an alleged multimillion-dollar theft and laundering conspiracy to a limited Section 641 offense involving only the thermal sights, our attorneys:
- Secured a resolution that substantially reduced the client's sentencing exposure and
- Eliminated the risk associated with the government's most serious charges.
The prosecution dismissed the broader conspiracy and money laundering allegations and did not attribute the full warehouse loss to the manager at sentencing.
Frequently Asked Questions (FAQs)
Reviewing these frequently asked questions helps defense contractors, service members, and logistics personnel quickly understand legal responsibilities, statutory thresholds, and defense options when military equipment is missing or questioned.
What is the main difference between 18 U.S.C. § 641 and UCMJ Article 121?
18 U.S.C. § 641 is a federal civilian criminal statute used in federal district court primarily against contractors and civilians, whereas UCMJ Article 121 (10 U.S.C. § 921) applies to active-duty military personnel tried under court-martial jurisdiction.
Can a civilian defense contractor be charged under 18 U.S.C. § 641?
Yes, Section 641 explicitly covers government property as well as any property made or being made under contract for the United States, making defense contractors and warehouse employees subject to federal prosecution.
How does the $1,000 threshold affect a Section 641 charge?
If the value of the property exceeds $1,000, the offense is a federal felony carrying up to 10 years in prison; if the aggregate value is $1,000 or less, it is charged as a federal misdemeanor carrying up to 1 year in prison.
What is the difference between larceny and wrongful appropriation under UCMJ Article 121?
Larceny requires proof that the accused intended to permanently deprive the military of the property and carries up to 10 years of confinement, while wrongful appropriation requires only an intent to temporarily deprive and carries a maximum of 2 years' confinement.
Is receiving or buying stolen military property also a federal crime?
Yes, under 18 U.S.C. § 641, anyone who knowingly receives, conceals, or retains stolen government or military property with the intent to convert it for personal use faces the exact same statutory penalties as the person who took it.
What are common legal defenses against military property theft charges?
Key defenses include showing a lack of criminal intent, that the property was transferred or used under valid contract terms or job authority, a good-faith mistake, or that the property was privately owned rather than government property.
