AFSOC’s AGM-190 Havoc Spear. U.S. Air Force special operators confirmed on Sept. 14 that a new low-cost cruise missile launched from a Lockheed Martin AC-130J met operational requirements during a recent test staged during a real combat operation in Africa. The live firings of two Leidos AGM-190 Havoc Spear missiles confirmed that the 400-nm-range, air-launched weapon is “accurate and effective” in the test configuration, Air Force Special Operations Command (AFSOC) said in a news release. The test involved firings on stationary targets. Further details of the combat operation were not released. “AFSOC Tests Cruise Missiles in Recent Combat Operation”, Aviation Week, September 14, 2026.

DoD Guidance on Testosterone Testing. The Department of Defense on Thursday released clinical guidelines for testing and treating low testosterone in male service members. The initiative, first announced in a July memo by Defense Secretary Pete Hegseth, is part of the agency’s Warfighter Performance Optimization program, which Hegseth announced in May. “Pentagon updates guidance on low testosterone testing for males”, Army Times, September 18, 2026. Read a DoD press release on the same topic. (September 17, 2026)

Greenland in the News. President Trump announced that the U.S., Denmark, and Greenland have come to an agreement on the U.S. posture on Greenland. The Trump administration has stressed that a new arrangement was needed in recognition of the strategic importance of Greenland. This new agreement seems very similar to the current agreement negotiated in 1951 and subsequent agreements. The 1951 agreement gave the U.S. access to 17 bases for as long as NATO exists. Since that time we have closed all but one of those 17 bases. The newly announced agreement does not appear to involve major changes to the existing U.S.-Danish defense relationship, although its final terms and implementation remain subject to formal approval. This agreement will bolster U.S. military presence there but keep the island under Danish control, after months of threats by the U.S. president to use military force to seize the semi-autonomous territory of a NATO ally.

Drones Have Impact on MEDEVACs. The introduction of drones into the modern battlefield has had an impact on the U.S. military’s medical evacuation procedure. Helicopters are not always used to evacuate patients as they are vulnerable to drones if forward based; in many cases ground transport is instead used for MEDEVAC or CASEVAC. The “Iran strikes exposed gaps in medical evacuation ops across Middle East: IG”, Defense One, September 15, 2026.

Fixing the Air Defense Problem. The use of cheap drones and cruise missiles in mass quantities by Iran has reduced the U.S. inventories of THAAD (NSI) and Patriot (NSI) interceptors across the globe. The number of Patriot battalions (15) is insufficient to meet the worldwide needs of the U.S. Read more in “Army Air Defense has a Problem, and It’s More Than Magazine Depth”, by Peter Mitchell, September 9, 2026.


Ukraine Russia Conflict


Ukraine Conflict

Ukraine

Ukraine launched its largest-ever drone strike against Russia, firing over 1,000 drones overnight. The historic barrage hit a critical oil refinery in Moscow and residential buildings, killing at least three people. The attack coincided with the final day of Russia’s three-day parliamentary elections, prompting Russian officials to accuse Ukraine of attempting to disrupt the vote.

Russia retaliated with massive aerial bombardments across Ukraine, deploying over 2,000 drones, 1,700 bombs, and 19 missiles this week. Meanwhile, the U.S. approved a $2.68 billion possible Foreign Military Sale for Kyiv. President Trump also signed sweeping new sanctions legislation targeting Russia’s energy, financial, and defense sectors.

Ukraine’s 3rd Army Corps has launched “Operation Vivaldi,” a ground counteroffensive in northern Donetsk. Striking the Lyman sector, Ukrainian forces liberated multiple settlements—including Shandryholove and Derylove—recapturing over 85 square kilometers.


Great Power Competition GPC


Strategic Competition

China’s Military Base in Djibouti. Not very far from the U.S. military base of Camp Lemonnier, Djibouti (map) is a People’s Liberation Army (PLA) Support Base. This installation provides the ability of China to conduct “far seas” operations well beyond China’s shores. Its intelligence-gathering capabilities have recently been enhanced. Opened in 2017, it supports PLAN Naval Escort Task Force operations in the Gulf of Aden and in the Bab al-Mandeb Strait. “Extended Range: China Upgrades its Military Base in Djibouti”, Center for Strategic and International Studies (CSIS), September 17, 2026.

AI, Trump, and Xi. Apocalyptic warnings about the danger of uncontrolled artificial intelligence are adding new urgency to talks between President Trump and Chinese President Xi Jinping set for next week. President Trump has dismissed the warnings members of the AI community and others have voiced – calling it a “hoax”. It is possible that conversations about AI safeguards and regulations may take place; but unlikely. The two leaders meet in Washington, D.C., on September 24, 2026. “AI fears burst onto Trump-Xi agenda, but challenges abound”, The Hill, September 20, 2026.

U.S. and China Seeking Strategic Stability? The United States and China are nuclear powers with enormous military forces, global economic relationships and overlapping interests. Neither should want accidental escalation, uncontrolled crisis or war. The upcoming meeting in Washington, D.C. will likely address many of the issues associated with attaining strategic stability. But the term could have a different meaning by the two parties. “Constructive strategic stability or strategic accommodation?”, by Dave Maxwell, UPI, September 14, 2026.

Around the World

Houthis Gain Ground in Yemen. The Houthis are continuing their offensive against government forces in their sweep south along the Yemen coast. This will extend their control over parts of the Red Sea and the Bab e-Mandeb Strait. The strait is a major global chokepoint where much of the world’s commerce transits – to include oil tankers.

A Regional Battlefield. The renewed Houthi attacks on Saudi Arabia are taking place alongside a much broader change in the security environment around the Middle East and Horn of Africa. This is a complicated region with competing factions. Irina Tsukerman examines the region in a detailed report entitled “How the Houthis Turned Saudi Arabia’s Flanks into a Regional Battlefield”, The Washington Outsider, September 16, 2026.

Controlling the Red Sea Coast. American officials have been meeting with a Houthi delegation in Oman to discuss the latest events in the Red Sea adjacent to Yemen and the Houthi’s advance southward along the Red Sea coast of Yemen. The Houthis are targeting Saudi Arabian shipping and oil infrastructure in Saudi Arabia. It is unlikely that the Houthis will agree to any U.S. overtures. “Letting the Houthis Control the Red Sea Would be a Gift to Tehran”, by Bridget Toomey, Foundation for Defense of Democracies, September 18, 2026.

Saudi Arabia Security Crisis. Irina Tsukerman explains in a long essay the current crisis that Saudi Arabia faces from the Houthis. Cheap drones and missiles launched from Yemen can strike critical targets in Saudi Arabia. Riyadh has a limited number of defensive air defense missiles as the six-month long conflict with Iran has depleted the inventory. Saudi Arabia has asked Washington and other nations for help; but thus far no real intervention against the Houthis has taken place. China has stepped in with a diplomatic effort to engage Iran; but that has not resulted in much progress. Read more in “Riyadh Under Fire: How Iran and the Houthis Turned Saudi Arabia’s Security Crisis Against It”, The Washington Outsider, September 19, 2026.

Fighter Jets to Saudi Arabia. The U.S. State Department has approved a possible $24 billion sale of 48 F-35A fighters to Saudi Arabia. This along with training, weapons support, and related equipment. A Department of State media release says that “This proposed sale will support the foreign policy and national security objectives of the United States by improving the security of a major non-NATO ally that is a force for political stability and economic progress in the Gulf region.” “Kingdom of Saudi Arabia – F-35 Lightning II Joint Strike Fighter”, U.S. Department of State, September 17, 2026.

U.S. Military Needs an African Shore. Jonah Brody and Maj Gen Robert Sofge argue that the U.S. needs access to ports and airfields in Somaliland and Puntland (map) to be positioned to address challenges to the freedom of navigation on the Gulf os Aden, Red Sea, and the Bab el-Mandeb Strait. “The Red Sea Fight Needs an African Shore”, Small Wars Journal, September 15, 2026.

Afghanistan’s FTP, CSTs, and Hope for a New Life in America. Read how American veterans are assisting former Afghan members of the Female Tactical Platoon stay in the United States after fleeing the Taliban in Afghanistan. Five years after the U.S. withdrawal from Afghanistan the FTP members are still in a legal limbo. “Afghan Women Fought With America, Now They’re Fighting to Stay”, Special Operations Association of America (SOAA), September 16, 2026.

Texts From August 2021 – Afghanistan. For two decades, we asked Afghans to stay beside us. Doing so placed their and their families’ lives within reach of retaliation by the Taliban. “I Still Have Hundreds of Texts From the Fall of Kabul. They Remind Me of the Promises We Broke”, by Tamara Geyer, The War Horse, September 17, 2026.




Veterans Corner

Paper on Veteran Population and Services. Katherine Kuziminski provides a detailed examination of the veteran population of America and the level of services available to veterans in different locations across the country. This is especially important for those attempting to determine how the veteran level of care was affected with the elimination of 30,000 positions within the Department of Veterans Affairs in 2025. “Redrawing the Map: Assessing the Military- and Veteran-Serving Nonprofit Sector”, Center for a New American Security (CNAS), September 15, 2026, PDF, 28 pages.

Podcast – The Stay Behinds: Sweden’s Cold War Guardians. Beginning in 1949, officially non-aligned Sweden did something it kept secret for half a century: in close cooperation with the CIA and MI6, it built a clandestine civilian resistance network meant to outlast a Soviet occupation and fight on from within. Its members were ordinary people, farmers, sales staff, gamekeepers, organized into cells that never met. In this episode, Johan Wennström of the Swedish Defence University, whose book The Stay Behinds: Sweden’s Cold War Guardians is the first in-depth English account of the network — details the tradecraft, the human cost, and why it suddenly speaks to a Europe at war and a Sweden newly inside NATO during the alliance’s most uncertain moment in a generation.
