The legal mechanism of procurement in Ukraine is defined by a number of regulatory documents, namely: The Law of Ukraine ‘On Public Procurement’ [1], Special Regulations No. 1178 [2], Special Regulations No. 1275 [3]. These regulations establish the legal and economic basis for the procurement of goods, works and services for contracting authorities, including ensuring their protection from military threats. Guided by them, procuring entities must proceed from the existing need for procurement or the need for the planned need for the next year.
