What is a special consideration regarding the VCE when conducting Table VI qualification?

The correct answer highlights a critical element concerning the use of Virtual Combat Environment (VCE) during Table VI qualification. Specifically, VCEs external to the battalion are required because they provide an objective measure of training and evaluation that supports the overall mission readiness of units. Utilizing external VCEs ensures that the training is not biased by the immediate tactical environment of the battalion, allowing for a more standardized and effective assessment of gunnery skills. This use of an external VCE can enhance the realism of the training scenario, providing better data for evaluating performance under conditions that are closer to actual combat situations.

In contrast, while VCEs can be useful at various command levels, having them external to the battalion allows for a clear separation and can prevent potential conflicts of interest that might arise if the evaluation is conducted internally. This separation can also encourage a more rigorous training environment where units can develop and demonstrate their capabilities without the influence of familiar surroundings or preconceived expectations.
