Saudi Arabia's military posture in Yemen centers on airstrikes and support for Yemeni government forces rather than direct ground incursions into Houthi-controlled Sanaa. Recent escalation since the July 2026 truce collapse includes Houthi advances seizing the Red Sea coast and Bab al-Mandeb strait in September, prompting Saudi-led coalition airstrikes on Sanaa and provinces such as Saada and Taiz, with dozens reported in early October. Riyadh is preparing a Yemeni-led offensive of up to 100,000 troops, backed by Saudi air power and US intelligence, focused on coastal and multi-front operations to regain strategic areas. No verified Saudi ground deployments toward the capital have occurred, and historical patterns show reliance on proxies amid high costs of direct intervention. Upcoming triggers include the timing of any offensive launch and cross-border exchanges.
