Practice Relating to Rule 25. Medical Personnel
Section B. Equipment of medical personnel with light individual weapons
Australia’s Commanders’ Guide (1994) provides that military medical personnel lose their protection “if they engage in acts harmful to the enemy … Protection will not be lost if medical members act in self-defence. Defensive weapons such as side-arms may be carried.” 
Australia, Law of Armed Conflict, Commanders’ Guide, Australian Defence Force Publication, Operations Series, ADFP 37 Supplement 1 – Interim Edition, 7 March 1994, § 615.
Australia’s Defence Force Manual (1994) states that medical personnel “are protected so long as they do not participate in hostilities. The carriage of light individual weapons for self-defence or for defence of wounded or sick in their care is not considered participation.” 
Australia, Manual on Law of Armed Conflict, Australian Defence Force Publication, Operations Series, ADFP 37 – Interim Edition, 1994, § 521; see also §§ 911 and 964.
Australia’s LOAC Manual (2006) states that medical personnel “are protected so long as they do not participate in hostilities. The carriage of light individual weapons for self-defence or for defence of wounded or sick in their care is not considered participation.”
