What ammunition was used by the enemy
During February 2026, the enemy, along with traditional means of fire destruction, used special ammunition equipped with irritant chemicals, in particular, used gas grenades such as K-51 and RG-VO, equipped with CS and CN chemicals. These grenades are anti-riot weapons.

In January 2026, the enemy regularly used special ammunition equipped with irritant chemicals, in particular, 224 cases of the use of dangerous chemicals were recorded.

CS and CN substances affect the temporary loss of combat capability
CS and CN substances in a number of states are officially used by law enforcement agencies exclusively in peacetime for law enforcement purposes, in particular control of riots, subject to strict compliance with certain norms and restrictions.
These substances do not belong to the list of lethal chemical warfare agents and are not aggressive solvents of equipment or personal protective equipment, nor are they intended for immediate lethal destruction of personnel.
These substances cause severe irritation of the mucous membranes of the eyes and respiratory tract, lacrimation, cough, suffocation, disorientation and temporary loss of combat capability.
In some cases, the symptoms of lesions described by military personnel may partially coincide with the manifestations of the action of other chemical stimuli, in particular anti-riot weapons or mixtures of unknown composition.
In accordance with article 1, paragraph 5, of the Convention on the Prohibition, Development, Production, Stockpiling, Use and Destruction of Chemical Weapons, the use of such substances as means of warfare is prohibited.
