Gulf States Conduct Joint Military Drill Amid Rising Regional Security Tensions

BAHRAIN SHIELD EXERCISE REFLECTS GULF STATES’ DEEPENING SECURITY CONCERNS AMID REGIONAL ESCALATION

The Bahrain Defence Force launched the joint military exercise Bahrain Shield on Tuesday, 28 July 2026, drawing together the armed forces of all six Gulf Cooperation Council member states for coordinated operations aimed at strengthening combat readiness across the region. The choice of name carries deliberate geopolitical weight, pointing directly to the strategic anxieties that underpin the exercise.

Bahrain occupies a particular position in regional power calculations. Iran has historically asserted territorial claims to the island state, and its Shiite-majority population creates what analysts describe as internal vulnerability. Since 1979, the Islamic Republic has positioned itself as the protector of Shiite Muslim communities throughout the Middle East, leveraging that role to build influence in Lebanon and Iraq while challenging the sovereignty of Gulf monarchies it regards as aligned with the United States and Israel.

The timing of Bahrain Shield reflects a period of acute regional strain. A 13-day confrontation between the United States and Iran, beginning 11 July, produced direct military strikes by both powers before a fragile ceasefire took hold. Iranian missiles struck multiple Arab countries during that window, including Jordan and Egypt. According to the New York Times, Iranian representatives allegedly claimed the attack on Egyptian targets was intended to demonstrate the disruption that could affect global energy supplies if Tehran escalated further. The strike on Damietta, in the Nile Delta, reportedly caused fires aboard two large vessels, signalling a potential expansion of the conflict beyond its traditional battlegrounds.

Meanwhile, the Bahrain Defence Force stated that the exercise was designed to strengthen joint defence cooperation, facilitate the exchange of operational experience, and assess shared military systems. Russian news agency RIA Novosti reported that the GCC’s unified military command aims to improve combat readiness to respond to any potential threat. The manoeuvres are intended to reinforce cohesion among the Gulf states and shore up regional security amid growing instability.

The GCC comprises Bahrain, Saudi Arabia, the United Arab Emirates, Kuwait, Oman and Qatar. Their combined gross domestic product amounts to approximately 2.36 trillion dollars, compared with Iran’s GDP of around 363 billion dollars. Despite that substantial economic advantage, the armed forces of the Gulf states have demonstrated only limited independent capabilities. Their principal security guarantee remains the presence of US military bases in the region, a dependency that has prompted consideration of alternative defence arrangements.

Recent developments have underscored the vulnerability of critical maritime infrastructure. The Houthis announced they had shot down a Saudi Karayel reconnaissance drone over Yemen’s Saada Governorate, with military spokesman Yahya Saree stating that forces would continue to defend the country’s sovereignty. The group has renewed threats to close the Bab el-Mandeb Strait, which links the Red Sea to the Mediterranean via the Suez Canal and represents one of the world’s most consequential maritime trade routes between Europe and Asia.

The strategic importance of that waterway has intensified as Saudi Arabia redirects approximately 70% of its oil exports to the Red Sea port of Yanbu, bypassing Iran’s blockade of the Strait of Hormuz. Data from Kpler and Signal Ocean indicate that around four million barrels of oil per day passed through Yanbu in recent weeks, up from fewer than one million barrels per day a year earlier. The total volume of oil transported through the Bab el-Mandeb Strait reached 7.4 million barrels per day in June, equivalent to roughly 7% of global oil production.

On 29 July, the Iraqi news agency NAA reported that four members of Iran’s Islamic Revolutionary Guard Corps were killed in a joint US-Saudi strike on the headquarters of the Popular Mobilization Forces in Iraq. The Saudi Ministry of Defence officially confirmed that the kingdom’s armed forces, in coordination with US Central Command, had struck targets belonging to Iran-backed armed groups in Iraq in response to Iranian drone attacks on Saudi oil-processing facilities.

The UAE’s experience defending against missile attacks, accomplished largely through Israeli air defence systems operated with assistance from Israel Defense Forces instructors, reflects the practical benefits of the Abraham Accords (which Bahrain and the UAE were the first Gulf states to sign). That normalisation with Israel reportedly weakened Iranian influence in both countries and may explain why Iranian missiles were directed at these states during the recent escalation.

The Gulf states now face a set of compounding questions: how to develop credible independent armed forces and defence industries, how to establish an effective unified military command, and how to identify supply corridors that are less exposed to disruption. The expansion of the Abraham Accords framework could open additional pathways for regional security cooperation. Whether those pathways prove sufficient, particularly if US military presence in the region contracts, is the question Bahrain Shield has placed squarely on the table.
