The development of ballistic missiles by Iran, or the export of advanced drones by Turkey, are ultimately the result of the American-led revolution in military affairs that, during the Gulf War, established the potential of precision guided weapons and reconnaissance systems. In response, America’s competitors have adapted their military doctrines and developed weapons designed to both counter and copy the West’s technological advantages. As the Government of Canada implements its defence policy—Strong, Secure, and Engaged—it has promised to procure a ground-based air defence system for the Canadian Armed Forces. Careful consideration and analysis are required, however, to ensure that Canada procures the best possible solution given limited funding and a wide array of potential threats.

2020 年的全球冲突凸显了通过发展军事力量意外使用先进弹道导弹和无人机。伊朗发展弹道导弹，或土耳其出口先进无人机，最终都是美国领导的军事革命的结果，海湾战争期间，这场革命确立了精确制导武器和侦察系统的潜力。作为回应，美国的竞争对手调整了他们的军事学说并开发了旨在对抗和复制西方技术优势的武器。随着加拿大政府实施其国防政策——强大、安全和参与——它已承诺为加拿大武装部队采购陆基防空系统。然而，需要仔细考虑和分析，
