Organisation A PSU consists of: 1 Inspector (red epaulettes) 3 Sergeants (white epaulettes) 18 Constables (black epaulettes) A PSU may be supported by: Police Medic - PSU Officer with advanced 1st aid training and equipment (green epaulettes) Evidence Gatherers - PSU Officers equipped with video recording equipment (orange epaulettes) Tactical Advisor - PSU Officers trained to advise the PSU Commander in lawful use of tactics (blue epaulettes) PSU grades All officers will be trained to the common minimum standards as defined in the ACPO Public Order Tactical Trainers Manual.

Level 1 - these officers (normally full-time PSU) receive regular specialist training which can be every five weeks including shield tactics, violent person, petrol bombing, crowd extractions and training in house entry and search. All public order officers need to be fit; a Level 1 officer must be able to run 1000 metres, dressed in full protective equipment whilst carrying a long shield, in less than 6 minutes. Level 2 - These officers are drawn from Boroughs/Divisions; they receive similar training to Level 1 officers but only in basic public order functions and tactics. Level 2 also only attend their specialist training centre two days a year for training. In some forces Level 2 officers must be able to run 500 metres dressed in full protective equipment whilst carrying a long shield in less than 2 mins 45 secs however this is no longer a national standard. If an officer fails any of the runs they are returned to their Borough/Division without receiving training or qualification. Officers are required to achieve 6.4 as a minimum on the bleep test to qualify for level 2. The long shields carried are 5'6" tall, 1'11" wide and weigh 17 lbs. Level 3 - All other police officers are classed as being level 3 trained, this they will have received in their last week at training school, their training includes all foot duty cordons, and mounted branch deployments.
