According to THIS video, at least 1 motorized brigade of the Saudi Armed Forces has been moved to the border with Iraq to conduct ‘military drills’ in this area.
Tihs action is a clear power play.
Сoncentration of forces and facilities at the Iraqi border means that the Saudi military grouping invoveld in the Yemen conflict has been weakened.
SouthFront: Analysis & Intelligence estimates the possibility that these forces will be moved to Syria as low. In this case, Saudi Arabia will be invoved in a two-front war which will be critical for the state already weakened by the dragged-out war in Yemen.
However, there is a chance that these forces and facilities can be used to form a joint force which could be sent to the Syrian front.
