Mo. Rev. Stat. § 41.270
All officers of the organized militia shall give bonds and security as may be required and within the time prescribed by the adjutant general to secure the state against loss on account of misuse or misapplication of state or company property or funds, or property or funds of the United States in use by the state. Such bonds shall be conditioned upon the faithful performance of all duties and the accounting for all property and moneys, including organization funds, for which the obligee is responsible or accountable. The adjutant general may, in lieu of the foregoing, enter into an agreement, conditioned in like terms and for the same purpose, with a qualified surety company to bond all officers of the organized militia without specifically naming them. The premiums on bonds shall be charged to funds appropriated for the support of the organized militia.
