Which document is used for issuing property from the unit's stock?

The correct answer is that DA Form 2062 is utilized for issuing property from a unit's stock. This form serves as a hand receipt that records the transfer of government property from a unit's stock to individuals or other units. It provides a detailed account of the property being issued, including descriptions, quantities, and condition of the items. This documentation is crucial for maintaining accurate inventory records and ensuring accountability of the property. Proper use of DA Form 2062 helps prevent loss and mismanagement of government property.

In contrast, the other forms listed serve different purposes within military logistics and inventory management. DA Form 2501 is used for processing government contracts, DA Form 3150 pertains to the inventory of property, and DA Form 3700 is related to logistical support and supply actions. Each of these forms has its specific function and does not directly address the issuance of property from the stock, which is why they are not the correct choice in this scenario.
