Tasers will be issued to every frontline police officer in Northamptonshire, in response to what's been called a "sickening trend" of attacks on the emergency services.
The force's Chief Constable Nick Adderley said the decision was not taken lightly, but was necessary to combat the threat of those who have no respect for law.
It will take 18 months to roll out and cost around £220,000.
As of March this year, there was 1,044 frontline officers in the force.
Mr Adderley said the weapons would be issued to all officers who want one.
He told the Daily Express: "I can't sit here and preside over a situation where my officers are exposed to increasing levels of violence when at my disposal is equipment that could save an officer's life.
"There are people out there who are prepared to seriously injure, or worse. We haven't moved with the times and we have to move with the times to combat the threat we are facing daily from those who simply have no respect for law and order."
Mr Adderley has previously called for Tasers to be standard issue within three years, but said he was "not prepared to wait".
The announcement follows the death of PC Andrew Harper in Berkshire, who was killed while investigating a burglary.
Issuing Tasers is a matter for each individual police force, but Police Federation of England and Wales national chairman John Apter said:
"We should ensure every officer who wants to carry a Taser can do so. Officer safety should never come second to balancing the books."
