The U.S. Army must be ready for its Falklands moment in the Pacific. All warfighting functions must adapt to operating in a region where the tyranny of distance spans half the globe. This article focuses on the intelligence warfighting function in the Indo-Pacific Command (INDOPACOM) theater. Previous commanders have described the Pacific as the most consequential theater.1 The most recent Office of the Director of National Intelligence (ODNI) Threat Assessment goes a step further and declares, “China presents the most comprehensive and robust military threat to U.S. national security.”2 The time to prepare for a crisis is now.

Intelligence provides vital functions, including maintaining situational awareness, targeting support, and setting the theater in support of operations.3 The 1982 Falklands War offers a valuable case study for analyzing these functions under conditions strikingly similar to what U.S. forces may face in a Taiwan scenario. Although a China invasion scenario is often the vignette of choice, a Falklands moment could manifest in a variety of unforeseen contingencies.4 This discussion assumes a U.S. response employing conventional forces. Using the Army’s four-step operations process of plan, prepare, execute, and assess, this article draws lessons from the Falklands conflict to inform today’s strategic imperatives. The intelligence enterprise must be organized and equipped today for war in the Pacific tomorrow.

The Falklands Conflict: A Strategic Primer

In 1982, Argentina launched a surprise invasion of the British-controlled Falkland Islands, located roughly 350 miles from the Argentine mainland.5 The islands were quickly occupied by a 10,000-strong Argentine force. In response, the United Kingdom deployed a combined naval task force to retake the islands. That force had to operate more than 8,000 miles from home with tenuous sustainment and contested sea lines of communication.

Despite logistical and political constraints, the British ultimately succeeded, incurring approximately 250 fatalities compared to Argentina’s 650.6 Advantages in joint integration, small-unit tactics, adaptability, and particularly intelligence allowed the British to overcome the challenges of distance and an entrenched adversary.

Argentine forces consisted of a mix of conscript and professional soldiers and were well armed, fielding modern French weapons, including the Super Étendard aircraft and Exocet anti-ship missiles.7 They also possessed a capable air force and, during one engagement, launched more than 70 aircraft against the British fleet. The surprise seizure of the islands allowed Argentina time to establish prepared defensive positions and operate with significantly shorter lines of communication than the British. Some of Argentina’s best units, however, remained fixed along the border with Chile as a deterrent, creating a strategic vulnerability.

In contrast, the British effectively leveraged intelligence to build an adaptable campaign plan and deceive Argentine forces regarding the actual location of the amphibious landing.

The British naval task force consisted of both military vessels and requisitioned civilian ships. Many of the British Army’s best units were mobilized to serve as the ground invasion force. While the British employed modern technology, including air defense capabilities, they were hindered by sustainment delays, and political considerations significantly shaped operational requirements.8 Despite these constraints, the task force leveraged advantages in leadership, small-unit tactics, and intelligence to execute a successful joint forcible entry. Their ability to shape the information environment while remaining operationally flexible provided tangible advantages against an adversary with first-mover advantage.

Joint operations conducted at scale across vast distances are among the most complex military endeavors.9 The U.S. Army in INDOPACOM must be postured to support the joint force under nearly identical conditions, and intelligence remains the key enabler.

INDOPACOM: A Falklands Refrain

Taiwan is located roughly 7,000 miles from California. Like the Atlantic in 1982, the Pacific Ocean offers few friendly staging bases. During the Falklands campaign, Britain relied on Ascension Island, which was remote but usable. In the Pacific, few options exist beyond Hawaii that are not within range of China’s strike and sensor systems.10

The People’s Republic of China is capable, determined, and focused on developing options for the forcible annexation of Taiwan.11 At approximately 100 miles from the mainland, Taiwan lies well within the reach of Chinese garrisons and firing positions. Aircraft and helicopters can sortie from home stations without requiring aerial refueling or intermediate staging bases. As in the Falklands, the defender must respond over extended lines of communication.

Just as Argentina benefited from proximity and surprise, China would hold advantages in mass, magazine depth, and rapid mobilization.12 The defender must overcome these advantages through superior planning, integration, and intelligence support to joint and coalition operations. A modern conflict would also require consideration of space and cyber domains, as well as the expanded role of unmanned systems. The central similarity remains the challenge of assembling combat power at distance while fighting through contested air and maritime domains. The intelligence principles that contributed to British success must be applied now, during peacetime.

The Intelligence Warfighting Function: Four-Step Analysis

Plan

As defined in Army Doctrine Publication (ADP) 5-0, The Operations Process, planning is the foundational command-and-control activity.13 Effective intelligence support begins long before conflict through rigorous planning, detailed wargaming, and honest assessment of capabilities and limitations.

In INDOPACOM, U.S. Army Pacific conducts operational rehearsals that include the forward deployment of sensors and personnel.14 These exercises stress assumptions and expose logistical challenges. As demonstrated in the Falklands, the force that plans effectively across land, sea, air, cyber, and space domains gains a decisive advantage.

Plans must also be realistic. British planners assumed certain platforms would be ready in time, and some were not. Similarly, U.S. planners must avoid reliance on systems still in development or testing. Access to intelligence, surveillance, and reconnaissance platforms in a contested environment must be assumed to be degraded and require redundancy.

Sequencing is equally critical. Improper sequencing during the Falklands campaign contributed to avoidable losses when assets were committed out of order. In INDOPACOM, failure to secure sea lines of communication or properly sequence collection platforms could result in catastrophic consequences. Integrated planning must impose multiple dilemmas on the adversary. The People’s Liberation Army (PLA) has numerous physical and virtual flanks, and forcing defense across multiple fronts, as Argentina was compelled to do with Chile, can dilute combat power.

Prepare

Preparation is more than training; it is a theater-wide posture. The intelligence corps must prepare by focusing on several key areas.

Training must reflect the Pacific fight. Units should tailor training to regional terrain, adversary doctrine, and electromagnetic threats. Analysts must develop deep regional expertise, including detailed order of battle analysis of PLA ground, air, cyber, and space forces.

Joint and partner integration is essential. Intelligence preparation must include information-sharing agreements, multinational targeting processes, and common operating picture development to ensure interoperability.

The intelligence architecture must be built, exercised, and validated. Theater-level intelligence data layers that feed the common operating picture must be resilient, redundant, and capable of operating in denied environments.

Finally, sensors and relationships must be prepositioned. Early access to collection is critical in contested environments. Forward-deployed sensors and analysts embedded with partners will be indispensable, and strategic relationships must be established well before crisis.

The British succeeded in part due to a culture of readiness. U.S. forces in the Pacific must demonstrate the same commitment.

Execute

Execution encompasses the conduct of collection, analysis, and targeting. During the Falklands campaign, British forces employed deception and strategic messaging to confuse Argentine commanders. U.S. intelligence units must be prepared to do the same.

Intelligence must directly support dynamic targeting cycles to enable joint fires and rapid decision-making. Timely intelligence is essential for disrupting PLA kill chains.

Processes must remain resilient under contested communications. Analysts at every echelon must be capable of conducting fusion and dissemination even when isolated. Distributed analytic nodes and edge processing will be critical.

Order of battle tracking remains fundamental. Understanding PLA composition, disposition, and intent across all domains will define mission success. Intelligence units must track not only maneuver forces but also logistics, electronic warfare, cyber units, and irregular formations.

Execution in INDOPACOM will be unforgiving. There will be no sanctuary.

Assess

Continuous assessment is not an after-action report but an ongoing feedback loop that adjusts intelligence focus, validates collection, and refines targeting priorities.

During the Falklands conflict, British commanders adjusted their plans based on real-time intelligence assessments. U.S. intelligence leaders must similarly assess gaps in collection and understanding, validate assumptions in operational plans and tactics, identify indicators of adversary deception or maneuver, and integrate feedback from tactical echelons into theater-level decision-making.

Commanders rely on intelligence to refine their understanding of the environment. Assessment keeps commanders informed and forces alive.

Conclusion

The Army plays a vital role in INDOPACOM. While the Pacific is often mistakenly viewed as a maritime theater, land forces provide the foundation for persistent presence, deterrence, and power projection. As demonstrated during World War II, land-based operations can determine the outcome of island campaigns.

The Falklands War offers a blueprint for how a smaller, determined force can succeed despite distance, delay, and surprise by leveraging intelligence, adaptability, and initiative. The U.S. Army intelligence enterprise must set the theater now through planning, preparation, execution, and continuous assessment to ensure that when crisis comes, the force is ready.

The Falklands should not be treated as a historical footnote — it should be a warning.
