Strengthening NATO’s Eastern Flank: Advisability on the UK Increase of its Troop Presence in Estonia

The debate on further increase in the number of UK troops in Estonia has gained steam, reflecting a wider security in Eastern Europe. Being integral to NATO’s Enhanced Presence (ePF), Estonia has been hosting the multinational troops led by the UK; with contributions from both France and Denmark. The eFP’s goal is to deter Russia from any kind of aggression and reinforces regional security. With geopolitical tensions mounting, there is increasingly a debate over whether the UK needs to expand its military presence in the Baltic Region.

Bolstering Deterrence and Alliance Cohesion

The Uk military presence in Estonia acts is a crucial deterrent against any potential aggression (UK Ministry of Defence, 2023). The UK leads NATO’s eFP battlegroup, signaling strong commitment to the collective defense of the alliance (UK Government Office, 2023). Advanced military equipment, air defense systems, and intelligence units were deployed, further enhancing NATO’s combat readiness along its eastern flank (Brooke-Holland, 2022). Furthermore, interoperability and confidence are enhanced by the historical cooperation between the British and Estonian militaries (Andžāns, 2016). The UK and Estonia have a long history of military cooperation, including joint operations in past conflicts. This close relationship facilitates operational efficiency and reinforces Estonia’s defense capabilities. Another positive side is that the UK can now go ahead and its heavy and serious training in Estonia (Jermalavičius and Billon-Galland, 2023). Indeed, the UK’s commitment to the mission has allowed its units to regularly rehearse and refine their own tactics in challenging environments, such as fighting in woods and forests, which has not been conducted in detail by the UK Army for over 20 years. Overall, the UK’s capabilities in deterrence, alliance cohesion and strategic placement are essential to ensuring the security and prosperity of not only the UK, but also its NATO partners.

Logistical and Strategic Limitations

Despite its strengths, the United Kingdom’s military deployment in Estonia must overcome many challenges. One of the most important limitations pertains to how well British military equipment is compatible with Estonia’s terrain (Lanoszka, Leuprecht and Moens, 2020). The forested and swampy terrains are not suited for the deployment of heavy armored vehicles, which are more appropriate for open battlefields. Furthermore, the UK force pre-deployment training does not fully replicate the conditions of Estonia (ibid.). Training in other places does not produce realistic settings that are equivalent to Estonia’s close woodland and wintery climate. Another area that needs improvement is the interoperability and integration of UK troops with Estonian forces. There appears to be a significant gap in tactical interoperability between UK troops and their Estonian counterparts (ibid). While UK forces are currently enabling integration of the Estonian Defence Forces (EDF) by working alongside them on UK-led exercises and maneuvers, the integration of UK forces into Estonian-led training is limited. Some UK troops have expressed that their time spent in Estonia would be more effective if they had the ability to train more frequently and closely with their Estonian counterparts (ibid).

Strategic Gains and Strengthened NATO Commitment

Enhancing the UK’s military presence in Estonia presents several opportunities. Firstly, it allows the UK to secure its strategic role within NATO and reaffirm its commitment to European security post-Brexit (Luik and Praks, 2017). By increasing the number of troops, the UK reaffirms its leadership role within the alliance and influence NATO’s long-term strategy in Eastern Europe and demonstrates the alliance’s commitment to defending its member nations. The long-standing cooperation between British and Estonian soldiers, including shared missions in Afghanistan, has fostered mutual trust and enhanced operational efficiency (Andžāns, 2016). Furthermore, British heavy armor and main battle tanks reinforce NATO’s defense capability. Repeatedly exercising in Estonia allows UK forces to practice tactics suitable for challenging terrain like forest warfare. Moreover, increased UK military presence in Estonia serves as a force multiplier, enabling more freedom of action and military planning (Jermalavičius and Billon-Galland, 2023). Lastly, Exposure to Estonia’s Russian-speaking minority (26% of the population) has also reinforced social relations and public trust in the NATO mission (Lanoszka, Leuprecht and Moens, 2020). The UK’s strategic presence remains vital to regional security and alliance cohesion

Potential Russian Escalation and Hybrid Warfare

Thought the increase of Uk troops in Estonia has security benefits, it also creates significant geopolitical risks. The first and foremost risk is that of retaliation (Andžāns, 2016). A greater UK presence might lead to an escalation in tension, along with asymmetric retaliation in the form of cyberattacks, economic pressure, or even military maneuvers (Estonian Foreign Intelligence Service, 2023). Another grave threat is information warfare. There has been manipulation regarding the NATO presence in the Baltics, causing division in the narratives. Allegations of discrimination against Russian-Speaking Estonians could be used to justify destabilization actions from Russia (Mix, 2019). A larger deployment by the UK would most likely heighten these narratives, thereby increasing the targeting of Estonia for propaganda and hybrid warfare mechanisms.

Enhancing the Effectiveness of UK Troops in Estonia

Several measures, if well placed, would minimize risks and further ensure that the UK’s increase in troop presence in Estonia is effective. Firstly, there should be an improvement in pre-deployment training: British troops must be better prepared for the environment that awaits them in Estonia. The army needs to introduce forest combat training and simulated winter warfare. Tactical interoperability must improve through increased and better integration with joint exercises, sharing commands, and communication between the UK and Estonia. The forces are also to implement proactive community engagements among the ethnic minority Russian-speaking Estonians who can help further Russian disinformation through enhanced social cohesion of Estonia. Finally, gradual deployment can occur based on consensus by NATO allies. This has a lesser threat to result in any strategic misalignment and unnecessarily provocation of Russia. There is a need to develop agile military strategies, with UK forces ready to meet both conventional challenges and changing hybrid –cyber– warfare.  These steps will reinforce deterrence, strengthen NATO’s eastern flank, and contribute to long-term regional stability.
