Section B. Equipment of medical personnel with light individual weapons
The Military Manual (1993) of the Netherlands provides:
Medical personnel may be armed with pistols, sub-machine guns and rifles, but not with machine guns or other weapons that have to be handled by more than one person, or with weapons that are meant for use against material objects, such as missile launchers and other anti-tank weapons, nor with fragmentation hand grenades and the like.

The Military Handbook (1995) of the Netherlands states:
Medical personnel may not in any way take part in hostilities, but they may be armed. They may, however, only use these weapons to defend themselves or the wounded and sick in their care and not, for example, to prevent being captured by the enemy. 
Netherlands, Handboek Militair, Ministerie van Defensie, 1995, pp. 7-40/7-41.
The Military Manual (2005) of the Netherlands states:
0618. Medical and religious personnel are non-combatants. They may not take part in hostilities. However, medical personnel may bear arms – see point 0621. If they fall into enemy hands, medical personnel are not considered as prisoners of war.
0621. In relation to medical personnel bearing arms, the rule is that they may carry a personal firearm such as a pistol, automatic pistol or rifle. Medical personnel may not be armed with machine guns or other support weapons. They must not bear weapons designed for use against materiel targets, such as rocket launchers and other anti-tank weapons, or fragmentation hand grenades, etc. They may fire their weapons in self-defence, for the defence of the wounded and sick in their care, and to preserve order and calm within the medical institution.
