Yemen: The Houthis make extensive use of Iranian anti-armor missiles to ambush armored columns of the Presidential Leadership Council forces In the early days of the war, the Houthis retreated from a vast area of Al-Jouf province, mostly an open plain, and concentrated their defense line where the enemy's air superiority is reduced. It also advanced on the southern front in Taiz province. The city of Taiz remains in the hands of the Presidential Leadership Council forces after weeks of siege by the Houthis, although urban fighting continues in its suburbs. In Marib province, Presidential Leadership Council forces made significant advances into Houthi-controlled areas early in the war, but their progress has slowed sharply as fighting expands into urban and mountainous areas and the risk of ambushes increases.
