Wage Assignment by Foreign Fighter
Ming Ma, a professional soldier hired by a foreign government, assigned his claim for unpaid wages from a completed mission to a creditor. The assignment fell outside Article 9 because it involved compensation of an employee under the governing exclusion. The creditor therefore could not perfect a security interest in the claim through the UCC filing system.
Expert Testimony on Combat Methods
Miles Montgomery, retained as a mercenary by a private military contractor, offered testimony on the reliability of certain battlefield tactics. The court applied the Daubert factors to assess whether his methods were generally accepted in the field of military operations. Because the testimony lacked independent research outside litigation, the court excluded it as unreliable.

Foreseeable Harm from Delayed Payment
Megan Moore hired Marco Marquez, a mercenary, to provide security services abroad. When payment arrived late, Marquez could not foresee the resulting lost opportunity to accept another contract. Under the rule governing consequential damages, the hiring party avoided liability for those remote losses.

Second Amendment Claim by Hired Combatant
Mercury Industries employed a mercenary to test weapons for a private security detail. When federal agents seized the weapons under a registration statute, the company asserted a Second Amendment defense. The Court upheld the seizure because the weapons lacked a reasonable relationship to a well-regulated militia.
