of the Army Medical Service, which all display the
red cross as a
protective sign, during a
military exercise, 2010 in
Afghanistan, wearing camouflage uniform When carrying out their
humanitarian function during
armed conflicts, medical personnel are
protected persons under
international humanitarian law, and are entitled under the
laws of war to carry out their work without being inhibited; they may not be attacked, harmed, taken as
prisoners of war or persecuted in any way; deliberately attacking or hindering medical personnel from performing their humanitarian work is a serious
war crime. Personnel are issued identity cards identifying them as protected persons under the
Geneva Conventions. Although personnel of the Army Medical Service are members of the armed forces and hold
military ranks, they are considered
non-combatants under international humanitarian law and thus enjoy protection and neutrality because of their humanitarian duties. The status of medical personnel as protected persons goes back to the 1864 Geneva Convention and was repeated in the subsequent Geneva Conventions of 1906 and 1929. It is currently set forth in the
First,
Second and
Fourth Geneva Conventions of 1949, their additional protocols and is recognised under
customary international humanitarian law, specifically by rules 25 and 26. Personnel of the Medical Service using the protective sign are prohibited under the laws of war from taking part in
combat action, and facilities or vehicles identified in that way may not be used for military operations. Medical units and personnel also lose their protection under international humanitarian law if they commit acts harmful to the enemy
outside their humanitarian function, as set forth e.g. by the First Geneva Convention, Additional Protocols I and II, as well as by rule 25 of customary international humanitarian law. However, medical personnel may be armed, usually with
service pistols, for the purpose of
self defense or the defense of patients, and their facilities (such as hospitals) may be guarded for the same defensive purpose. == Ranks ==
