ARP service personnel were issued with [[Brodie helmet|Mk. II British helmets]]. These were often not made to the same level as issued to soldiers to reduce costs. These helmets, which had less resistance to ballistic impact, would have small holes drilled in the rim to show they were not for front line use. Depending on the role of the person the helmet would be marked with a letter or letters to easily allow others to ascertain their role at an incident.
* W for wardens (some warden/fire guards had W/FG). Rank within the warden service was denoted by a white helmet and black bands.
* R for rescue services (later HR and LR were used for heavy and light rescue parties)
* RP for repair parties
* FAP for first aid parties and first aid posts 
* A for ambulance drivers
* M for messenger/runner
