I am trying to get as much info as possible with regards to the different roles I am interested in. I have found out a fair amount about CMTâs, and I understand the basic role of a Nurse. What I cant seem to find (and I have run searches) is the roles Nurses may or may not have in the field. Whilst I am aware they may work in field hospital, are nurses ever deployed in a more CMT style role? I.E Deployed with the patrols to handle battlefield casualties and get them back to the field hospital? I like the idea of the education behind the Nurse role, but I also like the idea of the CMT role being more in the thick of it.
