their regular colleagues. In some constabularies, their shoulder number may be prefixed with a certain digit or they may have additional insignia on their epaulettes which is usually a crown with the letters SC above or below it (although some forces just use the letters). Formerly, male special constables in English and Welsh forces did not wear helmets while on foot patrol but wore patrol caps instead, but in most forces they now do wear helmets. Some forces also issue special constables with a different hat badge from that of their regular counterparts although this is now extremely rare. Equipment Special constables all carry the same personal protective equipment (PPE) as their regular counterparts, such as handcuffs, batons, incapacitant spray (CS/PAVA spray), and protective vests. The issuing of equipment varies from force to force with financial factors being the main reason behind the differences. In some forces protective vests, or body armour, may be personally issued to an officer, made to measure, however many other forces cannot afford this practice and instead the use of pool sets is prevalent. The same practice is also seen with regard to radios: although many forces provide special constables with personal radios kept securely at their police station, other forces may only have pool sets. The management task is to ensure there are enough working pooled radios available in a command area to meet any "surge" need. On 19 May 2022, Home Secretary Priti Patel announced that special constables would be able to carry tasers. Prior to this, special constables were not issued or trained to operate tasers. The British Transport Police became the first force to issues tasers to special constables on 27 May 2022, starting a group of 22. Whilst not lawfully excluded from doing so, specials do not carry firearms due to enhanced vetting and the training commitments required. Powers and jurisdiction Territorial police forces The vast majority of special constables serve with one of the 45 territorial police forces in the United Kingdom. Depending on where they are attested, they have full police powers throughout one of three distinct legal systems - either England and Wales, Scotland or Northern Ireland. This is identical to the jurisdiction granted to regular officers, although prior to 1 April 2007, special constables in England and Wales only had jurisdiction within their force area and any adjacent force areas.
