When preparing a range card, what must the machinegun team provide?

When preparing a range card, it is essential for the machinegun team to provide a type of weapon and an 8-digit grid coordinate. This information is crucial for ensuring the effective placement and support of the weapon system. The type of weapon indicates the specific capabilities and range of the machinegun, which directly influences the planning and execution of fire support. The 8-digit grid coordinate is necessary for accurately identifying the location of the machinegun position; it ensures that friendly and enemy forces can be appropriately engaged with precision, minimizing the risk of friendly fire and maximizing the effectiveness of fire support.

Other options, while they may seem relevant in certain contexts, do not address the fundamental requirements for a range card, which is primarily focused on weapon specifics and accurate location data.
