The chemical army does not have the necessary equipment. According to the SAO, it cannot support the army
Between 2018 and 2022, the Ministry of Defence failed to ensure the necessary renewal and modernisation of the Army’s chemical warfare equipment. This follows from an audit by the Supreme Audit Office. For example, the authority did not purchase chemical spraying vehicles, decontamination equipment, vehicles for the removal of hazardous substances or anti-chemical isolation clothing. According to the auditors, the chemical army cannot comprehensively support the activities of the army’s combat units. In addition, it is also only partially meeting some NATO force capability-building objectives, despite the ministry’s commitment to meet them, the auditors said.
