Houthis’ Lesson for the U.S. Army: How a Land Force Can Fight a Maritime War
warfare and precision strike using weapons systems like PrSM and SM-6.
The army should apply the DMO concept to SMRF-equipped MDTFs and deploy them on bases outside the First Island Chain, the string of islands from Japan to Indonesia that hems in China.
This forward presence would contribute to integrated deterrence by forcing the Chinese military to cope with multiple operational dilemmas. It would, for example, have to track multiple distant targets simultaneously and defend against firing batteries distributed across the Western Pacific. Those batteries would demand attention because they’d have the range and lethality to strike and destroy high-value targets throughout the region.
A key aspect of Houthi operations has been the use of one-way attack drones—in effect propellor-driven cruise missiles that are extremely cheap and numerous, presenting unsustainable economic challenge, given the cost of defensive interceptors like SM-2s and SM-6s. Here too, the US Army can learn from the Houthis and adapt to use similar tactics. DARPA’s work, for instance, on offensive swarming drones will be a vital advance in how US thinks about and executes offensive maritime operations and sea control or denial.
To Houthi tactics, add strategic mobility. Here, the utility of the US Air Force’s heavy airlifters comes into play. They can deploy ground units almost anywhere that has even a rough airfield, greatly reinforcing the army’s ability to participate in an island-based maritime war. US and allied exercises should routinely practice rapid loading and unloading of systems such as HIMARS missile launchers on and off C-130 Hercules cargo aircraft.
A valuable effect of such exercises would be honing interoperability between US services and between them and allied militaries. Indeed, highly capable US allies, such as Australia, should play a major role in how the US Army and broader joint forces think about fighting in the Western Pacific.
The US Army and allied forces can achieve a war-altering advantage if they learn from and apply the Houthi tactic of controlling the sea from the shore with inexpensive drones and long-range precision strike weapons and if they blend this technique with air mobility.
The Houthis are unlikely teachers but teachers nonetheless. Houthi operations have demonstrated that shore-based sea control and sea denial can be highly effective. They have shown how the US Army and US partners and allies should incorporate new tactics and weapons systems into their forces before the next war comes.
