It is not uncommon for patrol officers to utilize a personal shield during dangerous procedures such as: high risk vehicle stops, approaching emotionally disturbed individuals, and building search and clearing operations. Determining what missions/situations would benefit from patrol use of a personal shield need to be established before the style of shield is selected for purchase. An example of an offensive/aggressive personal shield protected mission would be patrol response to an active shooter, with the intent to approach and neutralize the threat. Unlimited visibility, mobility, and the ability to accurately apply firepower from an appropriate handgun or long gun are required for active shooter neutralization.
