Latvia: Baltic Depth and Land Defence

Strategic Position and the Suwałki Problem¶

Latvia occupies the central position in the Baltic triplet — flanked by estonia to the north and lithuania to the south — and its strategic predicament is among the most acute in the alliance. The country is 64,589 square kilometres of largely flat, forested terrain with limited natural defensive barriers. Its capital, Riga, sits 300 kilometres from the Russian border at Pskov but only 50 kilometres from the sea, creating a vulnerability to coastal envelopment. More critically, Latvia shares 214 kilometres of border with Russia proper and a further 161 kilometres with Belarus — now fully integrated into the Russian military axis following the Union State’s activation as a staging area for the 2022 Ukraine invasion.

The Suwałki Gap — the 100-kilometre land corridor between Belarus and Russia’s Kaliningrad exclave running along the Polish-Lithuanian border — is the strategic pivot on which Baltic security turns. If Russian forces were to seize the Suwałki corridor, Latvia, Lithuania, and Estonia would be physically cut off from the NATO main body. Latvia, as the central Baltic state, would be encircled without a land link to allied reinforcement. This geographic reality has driven every major Latvian defence investment since 2014.

The Pre-2014 Baseline¶

Latvia’s defence forces were effectively hollowed out through the budget austerity of 2008–2013, dropping to 0.9% of GDP by 2012. The National Armed Forces (Nacionālie bruņotie spēki, NBS) maintained a nominal structure but lacked equipment depth, training throughput, or credible warfighting capability. Russia’s seizure of Crimea in March 2014 prompted an emergency reassessment. By 2016, defence spending had returned to 1.7% GDP; by 2018, Latvia became one of the first Baltic states to breach the 2% NATO target sustainably. The 2022 invasion of Ukraine accelerated the trajectory further.

Budget Trajectory and NATO Commitments¶

Latvia’s defence spending has grown from 2.0% GDP in 2018 to 3.1% in 2025 — among the highest proportional levels in the alliance. For 2026, Latvia has committed to maintaining above 3% as a floor, not a ceiling, with parliamentary consensus across the coalition that the threat environment does not permit fiscal retrenchment.

The Baltic states have collectively set the pace for European NATO members in translating political commitment into funded budget lines, contrasting sharply with Western European members that remained below 2% through 2023.

Force Structure: Regulars, Guard, and the eFP Battlegroup¶

National Armed Forces¶

The NBS comprises approximately 7,000 regular personnel organised around three primary manoeuvre elements: the Virsaitis Combined Arms Training Centre at Ādaži, the Latvian Land Forces’ mechanised infantry battalions, and specialist enabling capabilities including engineers, signals, and logistics. The regular component is insufficient for territorial defence by itself — Latvia’s strategic approach explicitly requires rapid mobilisation of the National Guard to provide mass.

The National Guard (Zemessardze) represents Latvia’s principal force expansion mechanism. At approximately 10,000 personnel, the Guard is a part-time territorial defence force with specific assigned sectors. Post-2022 reforms have accelerated Guard training, improved equipment holdings, and integrated Guard battalions more explicitly into the NATO eFP defensive scheme. Guard units are not merely a reserve backstop; they are the primary holding force in the event of attack, designed to impose cost and delay while regular NATO reinforcements flow through the Suwałki corridor — assuming it remains open.

Canada’s Enhanced Forward Presence Battlegroup¶

Canada leads NATO’s eFP battlegroup in Latvia, headquartered at Ādaži Base north of Riga. The battlegroup, established in 2017, has been expanded post-2022 from approximately 1,500 to over 2,000 personnel, incorporating contributions from Albania, Czech Republic, Iceland, Italy, Montenegro, Poland, Slovakia, Slovenia, and Spain alongside the Canadian framework nation.

Post-2022, Canada committed to expanding the battlegroup toward brigade scale — a formation of 3,000–5,000 personnel — in line with the NATO Madrid Summit decisions to upgrade all eFP formations. The Canadian-led grouping operates Leopard 2 MBTs alongside Latvian and contributing-nation mechanised infantry. Canada has also pre-positioned additional equipment stocks in Latvia to facilitate rapid reinforcement from Canadian Territory. The eFP battlegroup is a tripwire force: its purpose is to ensure any Russian attack on Latvia immediately involves Alliance member casualties, triggering Article 5 — not to halt a Russian offensive independently.

Equipment Acquisition: HIMARS and Precision Strike¶

HIMARS¶

Latvia contracted for six M142 HIMARS (High Mobility Artillery Rocket System) launchers in 2023, with deliveries completed through 2024. The acquisition gives Latvia a precision long-range strike capability that its land forces entirely lacked before: HIMARS firing M31 GMLRS rockets can engage targets to 84 kilometres with metre-level accuracy, while future integration of the Army Tactical Missile System (ATACMS) would extend reach to 300 kilometres — placing Pskov military district infrastructure at risk from Latvian territory.

Six launchers represent a modest but symbolically significant capability. The procurement fits within a Baltic-wide fire network concept: Lithuania, Estonia, and Poland all operate HIMARS or equivalent systems, and the combined fire mass of the Baltic-Polish defence corridor creates a deep-strike threat that complicates Russian operational planning along the entire northern axis.

Armoured Vehicles and MANPADS¶

Latvia operates Czech-built Pandur II 8×8 wheeled infantry fighting vehicles — 123 delivered — providing its mechanised infantry battalions with protected mobility and a 30mm cannon. The Pandur lacks the combat power of tracked IFVs like the CV90 or Bradley, but offers a practical capability for the mixed terrain of Latvian operational environments.

Air defence at the manpad layer is provided by FIM-92 Stinger missiles distributed across NBS and National Guard units. Latvia has also invested in HIMARS-complementary counter-battery radar capability, acquiring AN/TPQ-36 Firefinder systems to identify and engage hostile artillery — a capability whose importance was demonstrated repeatedly in Ukraine. Longer-range air defence remains a gap, addressed partially through the multinational BALTNET integrated air defence network and the coverage provided by Lithuanian NASAMS batteries to the south.

The Baltic Defence Line and Fortification Strategy¶

Following the 2022 invasion of Ukraine, the three Baltic states jointly announced the Baltic Defence Line — a fortification project spanning the Estonian, Latvian, and Lithuanian eastern borders. Latvia’s segment involves construction of anti-tank ditches, bunker complexes, pre-prepared fighting positions, and infrastructure hardening along the Latvian-Russian and Latvian-Belarusian borders. Funding of approximately €600 million across the three states was committed through 2027.

The fortification project reflects a doctrine learned directly from Ukraine: prepared defensive positions exponentially increase the cost of offensive operations. The Latvian terrain — pine forests, river obstacles, and marshland — is inherently defensible if positions are prepared in advance. The Baltic Defence Line is designed to slow, disrupt, and attrite an attacking force long enough for NATO reinforcements to arrive through the Suwałki corridor and by sea.

Gaps and Unresolved Problems¶

Latvia’s principal strategic gap remains the Suwałki corridor dependency. Even with improved fortifications and expanded force structure, Latvia cannot be defended in isolation if the land bridge to poland and the NATO main body is severed. The corridor’s defence falls to Lithuania and Poland, and to the credibility of NATO’s collective deterrence. Latvia’s own defence planning must therefore assume Suwałki remains open — a planning assumption that cannot be guaranteed in high-intensity conflict.

Secondary gaps include: insufficient organic anti-armour depth to defeat a sustained armoured thrust without air support; limited air defence above the MANPADS layer; naval capability that is effectively constrained to coastal mine defence and patrol; and a logistical infrastructure still adapting to the shift from Soviet-era rear-area organisation to NATO interoperability standards. Addressing these gaps is the central task of Latvia’s 2025–2029 defence investment cycle, backed by the 3.1% GDP budget.

Strategic Assessment¶

Latvia’s trajectory from 2014 to 2026 represents a coherent if incomplete security transformation. The combination of 3.1% GDP defence spending, a 17,000-strong force expandable through mobilisation, Canadian eFP leadership, HIMARS precision strike capability, and Baltic Defence Line fortification provides a deterrent posture qualitatively superior to anything Latvia could field a decade ago. The fundamental strategic vulnerability — dependence on the Suwałki corridor for any sustained defence — remains, and cannot be resolved by Latvia alone. It is a problem that requires the combined credibility of nato-eastern-flank deterrence and the physical solidity of lithuania’s corridor defence to address.
