The Hazardous Environment Combat Unit (HECU) is a specialized military unit designed to operate in dangerous and toxic environments. This includes areas affected by chemical, biological, radiological, or nuclear threats. HECU personnel are trained to handle hazardous materials and conduct missions that require advanced protective gear and equipment. HECU units often collaborate with other military and emergency response teams to ensure safety and effectiveness during operations. Their training includes survival skills, decontamination procedures, and the use of specialized technology. This unit plays a crucial role in maintaining security and responding to threats that pose risks to both military personnel and civilians.
