Staffordshire Police's firearms unit has been issued with Taser guns.
Capable of delivering a 50,000-volt shock, the single shot pistol-like weapons are designed to more safely subdue dangerous suspects who are believed to be armed, allowing officers to restrain them.
Staffordshire Police said the weapons will only be used by authorised firearms officers in situations where the deployment of weapons has been approved.
"We always try to resolve situations involving armed people safely and without force and the arrival of Taser in Staffordshire will not change that," said Assistant Chief Constable Suzette Davenport.
"However, if required, officers have a number of tactical options from which to choose, including the use of CS spray, police dogs, baton rounds and actual firearms. Taser simply gives us one more less-lethal option."
