Body Armour for Executives and Close Protection Officers | CloseProtectionHire

The debate about whether a principal should wear body armour almost always resolves to the same question too late: what is the assessed threat? Armour selection – like every other component of a close protection programme – starts with the threat assessment, not with the product catalogue.

Body armour for executive use has improved considerably in the past two decades. Materials that once required overt plate carriers – visible, heavy, incompatible with business dress – are now available in covert configurations worn under a shirt or jacket. That improvement has made armour a more practical consideration for executives in elevated-risk environments. It has also created a market of products sold on anxiety rather than need.

The Protection Level Framework

UK Standards: CAST

The Centre for Applied Science and Technology (formerly HOSDB, the Home Office Scientific Development Branch) publishes the UK’s body armour standards. CAST’s relevant standards are:

HG1 and HG2: Handgun protection. HG1 covers lower-velocity handgun rounds; HG2 covers higher-velocity handgun rounds including 9mm, .357 Magnum, and .44 Magnum. Most UK police soft armour is rated to HG2.

KR1 and KR2: Knife resistance. KR1 is the lower level; KR2 covers higher-energy knife strikes. These ratings are separate from ballistic ratings.

SP1 and SP2: Spike resistance (screwdrivers, needles, ice picks). Again separate from ballistic and knife ratings.

Combined (ballistic and stab) panels exist but add thickness and weight.

International Standard: NIJ 0101.06

The National Institute of Justice standard is the international benchmark most frequently used in product specification:

NIJ Level IIA: Designed to protect against 9mm and .40 S&W handgun rounds. Lightest protection level.

NIJ Level II: Protects against 9mm and .357 Magnum.

NIJ Level IIIA: Protects against .357 SIG and .44 Magnum. The standard threshold for executive covert armour. Provides meaningful handgun and fragmentation protection. Does not protect against rifle rounds.

NIJ Level III: Protects against 7.62x51mm NATO (.308 Winchester) rifle rounds. Requires hard plates – not compatible with covert carry under business clothing.

NIJ Level IV: Protects against armour-piercing rifle rounds. Heavy. Used in military and high-threat tactical contexts.

For most executive close protection in urban environments where the assessed threat is handgun or fragmentation (vehicle attack, IED proximity), NIJ IIIA or CAST HG2 is the working standard.

Materials: Why Modern Armour Is Lighter

The weight reduction in contemporary soft armour is primarily attributable to two materials:

Dyneema (UHMWPE – Ultra-High-Molecular-Weight Polyethylene): A Dutch-developed fibre (DSM, first commercial armour application in the 1990s) with a strength-to-weight ratio approximately 15 times that of steel. Used in both soft and hard panel construction. Dyneema HB26 panels are rated to NIJ IIIA at 4-5mm thickness.

Spectra (Honeywell): The US-equivalent UHMWPE product, broadly comparable in performance to Dyneema. Both products have been extensively tested and validated by NIJ and CAST.

These materials replaced earlier heavy Kevlar (para-aramid) constructions that made extended covert wear impractical for anyone who needed to maintain business dress and mobility over a full working day.

Covert Armour in Practice

A covert vest rated to NIJ IIIA worn under a business shirt and jacket is not visible to a casual observer. The profile under a well-fitted jacket is comparable to wearing a thermal layer. The key practical considerations are:

Climate: In warm or humid environments, body armour significantly increases heat retention and sweating. This affects both comfort and compliance. The executive who removes the vest in a car between venues because it is uncomfortable has reduced their protection to zero in the transitions – which are typically the highest-exposure moments.

Duration: A full day’s wear in business dress is achievable with modern materials but requires the principal to be briefed on the discomfort and the importance of consistent wear.

Fit: Armour that does not fit correctly migrates during movement, creating gaps in coverage and increasing discomfort. Professional fitting by a specialist supplier is essential. The armour should be fitted to the principal, not selected from a general size run.

Coverage: A standard covert vest covers the torso – front and back panels. It does not protect the arms, legs, neck, or head. For environments where fragmentation is the assessed threat, side panels that extend lateral coverage are available.

When Overt Armour Is Appropriate

In environments where concealment is not the priority – or where the threat level justifies accepting a higher profile in exchange for greater protection – overt armour worn over clothing provides higher protection ceilings and better ventilation.

Close protection teams operating in environments such as active conflict adjacency, high-threat travel corridors in Mexico City, Karachi, or Lagos, or specific event security contexts where an attack has been assessed as credible, may operate in overt plate carriers with Level III or Level IV hard inserts.

The decision to operate overtly armoured is itself a profile decision. A close protection officer in a plate carrier changes the visible security footprint of the principal’s movement. In some environments this is a deterrent. In others it signals the presence of a high-value target.

Legal Position: UK and International Travel

United Kingdom

There is no general prohibition on purchasing, possessing, or wearing body armour in the UK. The Criminal Justice Act 2003 Section 141A restricts possession in some specific court-ordered circumstances, but does not apply to lawful civilian use.

Body armour is not a controlled item under the Firearms Act 1968, the Offensive Weapons Act 2019, or any general weapons legislation.

However, carrying body armour onto commercial aircraft is subject to airline and airport-specific rules. It is not generally prohibited as carry-on luggage but should be declared and the armour panels removed from their carrier for screening.

International Travel

Several countries impose restrictions on civilian body armour:

Brazil: Civilian possession of body armour is restricted. Brazilian law requires a permit. Executives travelling to Brazil should not carry armour without obtaining specific legal advice.

Some Gulf states: Import restrictions apply. The position varies by country and should be verified with legal counsel before travel.

Ukraine (current conflict period): Civilian armour importation restrictions apply given the conflict context.

The safest approach for any international executive travel with body armour is to obtain jurisdiction-specific legal advice before departure and, where possible, to source armour in-country through a verified local security provider rather than carrying from the UK.

Close Protection Team Armour

Whether the close protection team is armoured – and to what specification – is a separate decision from whether the principal is armoured. In most corporate close protection operations in lower-threat environments (London, New York, Singapore), the team operates without armour to maintain a low profile.

In elevated-threat environments, team armour decisions consider:

Role-specific threat: The close protection officer in the principal vehicle is in a different threat position from the advance officer on foot. Role-specific armour specification is appropriate.

Mobility: An officer in overt plate carrier has reduced mobility compared to an unarmoured officer or one in a covert vest. In environments where rapid movement is more likely to resolve a contact than ballistic protection, lighter configurations may be preferred.

Consistency with principal: An armoured principal accompanied by an unarmoured team creates a logical gap. Conversely, a fully armoured team accompanying an unarmoured principal may signal the threat level to hostile observers.
