Firearms Officer
AFO/ARV Explained

England, Wales and Scotland maintain one of the few large, developed policing models in the world where the great majority of officers do not routinely carry firearms. Armed capability is instead concentrated in a relatively small proportion of trained, specifically authorised officers who can be deployed where and when a firearms threat requires it, rather than issued universally.

This model shapes almost everything about the AFO role. Because armed capability is a deliberately limited, opt-in specialism rather than the policing default, the selection bar, the training investment per officer, and the ongoing accountability expectations are all set significantly higher than for general duties — the service is trading numbers for depth of training and scrutiny.

It also means AFO numbers, deployment patterns and firearms authorisation policy shift over time in response to the national threat picture (including counter-terrorism planning), which is one reason firearms recruitment can open or tighten at different points depending on force and national priorities. Check your target force's current careers page for live vacancy status rather than assuming firearms recruitment is permanently open.

Most of an AFO's working time is not spent discharging a weapon — the vast majority of a career is spent on patrol, responding to lower-risk incidents that happen to fall within an armed unit's area, and providing a rapid-response capability that is available if a firearms threat emerges. It is closer to specialist response policing than to anything depicted on television.

A typical armed shift includes:

• Briefing and weapon checks: Every shift starts with a formal briefing, a function check of firearms and equipment, and confirmation of the day's authorisation and threat picture.
• General patrol and support: Crewing an ARV to provide cover, backing up unarmed colleagues at higher-risk jobs, and attending incidents that may escalate.
• Planned operations: Pre-planned deployments such as warrant executions, high-risk arrests, or protection duties, briefed and authorised by a Tactical Firearms Commander in advance.
• Spontaneous deployments: Responding to firearms or weapons incidents as they are reported, under the direction of a Bronze/Silver/Gold command structure.
• Administration and continuation training: Logging authorisations, completing use-of-force paperwork after any deployment involving a weapon being drawn (not just discharged), and attending mandatory refresher sessions.

A defining feature of the role is that drawing a firearm — not just firing it — is itself a reportable, recorded event in most forces, reflecting how tightly regulated the specialism is compared with general patrol.

Firearms authorisation is also a prerequisite for several close-protection and dignitary-protection roles, which sit alongside ARV/SFO/CTSFO as their own distinct specialisms rather than an automatic extension of them. These include royalty and specialist protection functions and diplomatic protection duties, each with their own additional selection process on top of a firearms authorisation. They are typically smaller, more competitive units than general ARV posts, and are usually only open to officers with an established firearms and, often, surveillance or protection-adjacent track record.

Firearms selection is run separately by each force against a shared national training curriculum, so the exact eligibility bar varies. That said, the common baseline requirements you will see across the great majority of forces are:

• Substantive Police Constable: Off probation and confirmed in rank — this is not a route into the police, only a specialism for serving officers.
• Minimum service: Many forces expect a minimum period of general operational experience first (commonly cited around two years, though this is locally determined) so you have a track record to draw on under pressure.
• Fully deployable: No restrictions, adjustments or health issues that would prevent immediate operational firearms duties.
• Higher vetting clearance: Firearms roles require vetting that goes beyond the standard level, reflecting the access, authority and risk involved.
• Enhanced financial checks: Outstanding County Court Judgments and undischarged bankruptcy are typically treated as an automatic bar for armed roles, more strictly than for general policing, reflecting corruption and coercion risk.
• Eyesight and medical standards: A specific firearms medical, including eyesight standards that go beyond the general recruitment medical.
• Fitness standard: A pass at JRFT Level 9.4 on the 15-metre bleep test, well above the general service standard.

Firearms capability is not organised identically everywhere. Some smaller forces maintain their own dedicated ARV capability; others enter regional collaboration agreements, pooling firearms resource with one or more neighbouring forces to make round-the-clock, geographically spread cover viable without every force separately funding and training a full armed unit.

What this means practically for a candidate: firearms vacancies, unit structure and even which force actually "owns" the ARV you'd be posted to can differ significantly depending on where you serve or apply. Always check the specific structure of the force (or regional collaboration) you're interested in, rather than assuming a single national model.

Passing initial training is not the end of the assessment — it is the start of a career-long cycle of requalification. AFOs must requalify regularly (typically annually, though the exact cadence is set by each force against national standards) on marksmanship, tactics, fitness and legal knowledge. Failing a requalification suspends the authorisation until the standard is met again, or, if it cannot be met, ends the individual's firearms role while their substantive career as an officer continues.

Continuation training also covers use of force law in detail — the legal framework under which any decision to point, draw or discharge a firearm is judged, both operationally and afterwards in any investigation.

If you are already an AFO and want to move force, most forces run a dedicated armed transferee route, distinct from a standard transfer. This generally requires you to be currently deployed in the role (not just previously qualified), off probation, and fully deployable, and it usually adds a further interview, a firearms-specific medical questionnaire and deeper vetting on top of the standard transfer process.

The accountability burden is genuinely higher in firearms roles than almost anywhere else in policing. Any police shooting is automatically referred to the Independent Office for Police Conduct (IOPC), regardless of the circumstances — this is standard practice, not an indication that anything went wrong, but it means every AFO accepts a much greater likelihood of formal scrutiny, and potentially a lengthy investigation, as a normal feature of the role.

Even drawing (not firing) a weapon typically triggers a recorded, reviewable entry. Officers are trained and supported to document their decision-making at the time, precisely because those decisions may be examined in detail — sometimes years — later. Forces provide welfare and occupational health support specifically for officers involved in a critical incident, recognising the psychological toll this can carry.
