Perimeter Control
Another common challenge tactical teams face is subjects exiting and reentering a structure. When teams are authorized to use non-lethal force to prevent the subjects from reentering the structure, the most common tools used to control these subjects are impact munitions.
Whether launched from a 12-gauge shotgun or a 37mm or 40mm launcher, these projectiles are often very successful at knocking the suspect down and they give the operator the greatest standoff distance of any non-lethal option commonly available. However, these weapons are not always effective at putting a subject down and, even when they do, it is usually temporary and requires that the team move up quickly to take control of the suspect or the operator needs to deploy additional rounds. The injury profiles associated with multiple strikes from these weapons can be significant.
TASERs have been used frequently and very successfully to prevent subjects from reentering structures. Once the suspect is incapacitated, they are less likely to get up than they are after being struck by an impact round. And if they do attempt to get up, additional cycles can be used to keep them down without causing additional injuries.
The greatest limitation of the TASER in this situation is its maximum effective range of 35 feet. However, depending on the terrain, the availability of cover, and the suspect's movements, operators often find themselves within 35 feet of the suspect. With armored vehicles becoming more available, these close-in perimeter positions are becoming more common. As mentioned earlier, the maximum range of ECD devices will soon be extended with the introduction of the XREP.
