defence capability, reinforcing the safety of Estonian people and deepening their patriotic education. Units of the Defence Forces are ready to commence military defence on the mainland, at sea and in the air and the cyberspace, even when an attack is unexpected. To guarantee a timely response, the state has an efficient early-warning system, a flexible legal base and the modern mobilisation and apprisal systems. In order to make the mobilisation system more efficient, reservist training and additional short-notice reservist training assemblies will be held regularly and contemporary apprisal system used. Capabilities that can be used to notify Estonian residents and the wider world about what is happening in the event of attack will be developed. Cyber warfare is an integral part of military defence and cyber security. The private sector and volunteers will be involved in these activities. Estonia’s defence is foreseen as a collective defence operation under Article 5 of the North Atlantic Treaty. The prerequisites of credible deterrence and defence are the unity and solidarity of allies, which are constantly demonstrated.

NATO must be capable of immediate collective counteraction everywhere on the Alliance’s territory—on land and sea, in the air and the cyberspace - to make deterrence credible.

In order to maintain credible deterrence and defence of the Baltic region, combat-ready units must be stationed in the Alliance’s territory, including Estonia, and organisation must be capable to deploy more forces to the area if necessary. The allied military presence must be permanent and involve several allied countries, and the forces must maintain interoperability with Estonian units. Estonia participates in collective defence and other military operations outside its territory to maintain the security of all its allies. The prerequisites of the redeployment of allied forces are the rapid-reaction units and plans for their deployment, an efficient early warning system, swift decision-making and highly capable Host Nations Support system. Estonia together with its allies will guarantee the infrastructure that meets the needs of hosting allied forces is in place and conforms to requirements, and ensures the provision of Host Nation Support and training areas. Estonia engages in bilateral and multilateral defence cooperation to strengthen NATO’s collective defence and Estonia’s individual defence capability, and to promote stability and security in Europe and its vicinity. Estonia wants to involve partner states that are not NATO members in the defence of the region through NATO, the European Union and other forms of bilateral and multilateral cooperation. 3.3 Protection of Constitutional Order and Law Enforcement The foundation for safety is a safe living environment.
