2.6.3 Certain Mutual Respect Between Opposing Military Forces. Honor demands a
certain mutual respect between opposing military forces.
Opposing military forces should respect one another outside of the fighting because they
share a profession and they fight one another on behalf of their respective States and not out of
personal hostility.121 For example, this principle is reflected in the rule that POWs are legally in
the hands of the enemy State and not the individuals or military units who have captured them.122
2.6.3.1 Honor and Rules for POW Captivity. In demanding a certain mutual
respect between opposing military forces, honor animates rules that relate to the treatment of
POWs. For example, honor is one of the foundations for the humane treatment of POWs.123
The principle of honor is also reflected in rules that require POWs and their captors to treat one
another with respect. For example, POWs must be treated with respect for their honor and
person.124 As another example, POWs, with the exception of officers, must salute and show to
all officers of the Detaining Power the external marks of respect provided for by the regulations
