Attrition, Exhaustion, and Escalation: Do Houthi Calculations Transcend Territorial Control?

With the widening scope of clashes between government forces and the Houthis, the trajectory of the war in Yemen is no longer governed solely by areas of geographic control. Instead, it has become linked to each party's ability to continue operations and bear their military and economic costs, amidst an extended institutional crisis.

Developments in Taiz and the western coast, coinciding with battles raging in Marib and Al Jawf, reveal an overlap between objectives of geographic expansion and calculations aimed at exhausting the adversary and limiting their capacity for initiative.

While government forces, through Operation "Dawn of Yemen," work to regain strategic positions, target Houthi movements and reinforcements, the militia seeks to consolidate its gains and intensify pressure on government-held areas, imposing additional burdens on them regarding defense, supply, and redeployment.

These movements gain significance from the location of fronts where roads and highlands overlooking reinforcement lines and coastal areas near Bab el-Mandeb intersect, making any field advance or retreat have an impact that transcends the boundaries of the area involved in the fighting.

In this context, Houthi movements appear distributed across two overlapping tracks: expanding presence in strategically important areas, and strengthening the negotiating position by raising the cost of continuing the war for the government and its allies. However, achieving this remains contingent on the militia's ability to hold its positions and face counterattacks, versus the government forces' readiness to address their imbalances and build on their gains.

Resources and Capabilities
The fronts in Taiz form a clear example of the overlap between geographic control and troop exhaustion; the impact of Houthi advances in the southern countryside of the governorate is not limited to expanding influence but extends to besieging the city and complicating the arrival of supplies to it. This makes it difficult for government forces to secure supply routes and organize counterattacks.

The importance of the western and southern highlands located between Taiz and Lahj grows, given their commanding position over supply routes and movement axes towards the western coast and the vicinity of Bab el-Mandeb.

The militia seeks to secure its coastal positions by expanding its deployment in the Taiz countryside and surrounding highlands, giving it greater ability to pressure government forces and their communication lines.

Through this advance, the Houthis attempt to weaken one of the most prominent centers of government influence in Taiz and open pressure axes towards other areas. However, converting these gains into broader progress remains linked to the militia's ability to secure new positions and face reverse attacks, as well as the extent of government forces' ability to prevent the establishment of new Houthi control lines.

The continuation of confrontations on distant fronts imposes real challenges on government forces, which need to distribute personnel, equipment, ammunition, and logistical support while retaining troops capable of intervening when new breaches occur.

But conversely, this equation is not without cost for the Houthis themselves, as expansion requires securing new positions and supply lines, distributing forces over wider areas, alongside facing airstrikes and counterattacks.

Varying Capabilities
Military pressure does not stop at ground operations but extends to the use of drones and missiles to target military sites and vital facilities, adding an economic dimension to the confrontation.

While government forces rely on multiple ground formations and benefit from air support provided by their allies, the Houthis have accumulated experience in using missiles and drones and executing remote attacks, alongside exploiting the nature of the terrain in managing confrontations.

This disparity in combat means and support is a factor influencing the determination of operation costs and outcomes, without implying absolute superiority of either side in overall military capabilities.

However, the disparity in weapon costs does not mean that the attrition balance works in one direction, or that reliance on low-cost offensive means guarantees sustainable superiority.

Continuing these attacks requires supplies, operational capabilities, maintenance, and compensation for losses. Moreover, government strikes supported by air power may also impose human and material losses on the Houthis, pushing them to redistribute their forces or change their positions.

Hence, the impact of these means is linked to the Houthis' ability to maintain the pace of attacks, versus the ability of government forces and their allies to protect vital sites, minimize damage, and continue targeting military movements and supply sources that help the militia continue its operations.

Decisive Factors
The ability of government forces to confront is affected by existing imbalances within the military institution, foremost among them the multiplicity of formations and the variance in command structures and priorities, alongside financial and logistical constraints facing the state.

Challenges reflect directly on field performance, as managing confrontations requires coordination between military units, the ability to transfer troops between fronts, and directing supplies to the most needy axes, in addition to unifying operational decision-making and determining priorities according to field developments.

This problem overlaps with the difficult financial situation facing the government following the halt of Yemeni oil exports since 2022 and the decline in public revenues. According to the World Bank, this has caused a narrowing of the state's ability to finance basic expenditures, including salaries and services.

On the other hand, the Houthis rely on collection revenues in their controlled areas to fund their military, security, and administrative apparatuses, reflecting differences in funding sources and the nature of financial obligations for both parties.

This reality limits the financial maneuvering margin available to the government and makes the continuation of military operations more closely linked to the availability of external support and regularity of supplies.

Regional Pressures
Houthi escalation transcends the boundaries of internal fronts to an attempt to raise the cost of military support received by the government from its regional allies, through targeting interests and vital facilities in the Kingdom of Saudi Arabia.

According to a report by the International Crisis Group, attacks targeting Riyadh Airport and other Saudi facilities appear to be an attempt to send a message that continued military support for Yemeni government forces will result in increased security and economic costs for the Kingdom.

The report views that prolonging the confrontation may exhaust the Houthis' own capabilities, which may explain their pursuit of rapidly raising the cost before the conflict turns into a long war of attrition.

But the same report warns that this approach may backfire, after the attacks contributed to reinforcing Saudi Arabia's determination to continue the confrontation and intensify support for government forces.

Thus, attempting to raise the cost of war on the supporting side may not be sufficient to reduce its support, but rather push it to increase military support and expand coordination with partners, given the link of the western coast and Bab el-Mandeb fronts to international maritime passages.

Ability to Continue
At a time when current developments place the war in Yemen before an equation that transcends control of positions, without negating the importance of land as a basis for any change in the balance of power, the field pressures imposed by the Houthi militia do not guarantee automatic military resolution or political gains.

Similarly, the success of government forces in regaining strategic positions alone is not enough to change the course of the war unless coupled with consolidating gains, unifying military decision-making, improving resource efficiency, and preventing the recurrence of breaches on other fronts.

Between these two paths, the equation will not be decided by the number of positions controlled by any single side alone, but by its ability to continue the war and bear its cost, and the extent of its success in converting field influence into sustainable gains without draining resources and capabilities.
