by Kris Osborn, President, Center for Military Modernization Undersea drones, amphibious attack, land-based ocean attacks, submarine surveillance and integrated land-sea operations continue to be a growing focus for the US Marine Corp and highly amphibious special units such as US Navy SEALs, as the threat environment increasingly requires an ability for combat forces to transit across undersea, coastal and island areas for multi-domain operations. Following years of land-centered operations, the Marine Corps has in recent years been accelerating a shift to its maritime roots and multi-domain land-sea combat operations. The same is true of the Navy SEALs. This means more island-hoping, amphibious attack operations, coastal land-sea patrols and missions and more multi-domain connectivity and manned-unmanned operations. These increasingly prioritized amphibious attack concepts of operation, something becoming increasingly vital in the Pacific, has been driving the Corps to acquire and prioritize weapons systems and technologies capable of functioning in both a maritime and land-war environment. The Corps is setting up a special maritime Pacific regiments and the Navy SEALS have for years prioritized ocean-land combined reconnaissance, hostage rescue and attack operations. This helps explain why the Corps is acquiring a new high-speed, multi-domain Medium Amphibious Ship for Island hopping and sea-land operations and tailoring, adapting and acquiring weapons systems able to operate in undersea, surface and land combat environments. The Glock 19 is no exception, as its ability to function underwater is a key reason why its popularity among Navy SEALs and Marines continues to grow, Glock 19 ******** The Glock 19 has quickly become a favorite of the U.S. Navy SEALs for the sidearm’s ability to function underwater, better shooting capabilities, and being less prone to corrosion. The Glock replaces the SIG P226, which is being phased out over time. ENTER THE GLOCK 19 The Glock 19 has emerged as the preferred firearm [https://www.usamm.com/blogs/news/why-do-navy-seals-use-a-sig-p226#:~:text=In%202015%2C%20the%20Glock%2019,primary%20handgun%20of%20the%20SEALs.] of the special military unit. The Sig P226 continues to be slowly phased out. The Glock 19 is largely preferred and celebrated by Navy SEALs, in large measure because it performs much better in salt water. The Navy SEALs regularly operate in such environments, and a more durable sidearm greatly enhances the operational capacity and range of missions. The merits of the Glock 19 also include cleaning and maintenance. “I’ve worked on Sig P226, and they are harder to clean, and some of their springs have a terrible habit of rusting. Also, SIGs are single-action/double-action, decocker guns, while Glocks are striker-fired. They tend to have a more consistent trigger, and there is Glock’s reliability to consider,” explained Mike Myers in an article for Spec Ops Magazine. “When fitted with maritime cups, Glock 19 is one of the few handguns that will function and cycle reliably underwater.” The SEALs and other forces such as the Marine Corps are increasingly thinking in terms of multi-domain tactics, given advances in technology, tactics, and the demands of missions. The Marine Corps, for example, is traditionally an amphibious-based unit, yet the advent of drones, unmanned systems, and weapons systems capable of transitioning and functioning in both land and sea environments has strongly reinforced Navy SEAL and Marine Corps versatility in a multi-domain operational scope. Therefore, it is not surprising that Special Ops Magazine finds similar reverence and support for the Glock 19 has also reached the Marine Corps. In recent years, the Corps has focused on tactics and concepts enabling a more complete return to its maritime roots, following years of largely ground wars in Iraq and Afghanistan [https://www.marinecorpstimes.com/off-duty/military-culture/2021/12/24/in-the-shadow-of-alexander-the-great-a-marine-grunt-looks-back-at-iraq-and-afghanistan/]. Fighting Terminator: Army Prepares to Fight Robots For example, the Marine Corps has in recent years been developing new variants of weapons such as the Naval Strike Missile able to attack from both sea and land positions. In addition, Marine Corps Force Design 2030 [https://www.marines.mil/Force-Design-2030/] emphasizes tactical synergies between unmanned systems and lighter, more expeditionary yet lethal weapons capable of moving power and weaponry across domains in a land-sea warfare environment. These concepts of operation are also why the Corps has been pursuing its Medium Amphibious Vessel, a smaller, faster, more mobile amphibious assault platform engineered for multi-domain, amphibious, sea-land operations such as island hopping and delivering Marines and Special Operators such as Navy SEALs in littoral, coastal, island and sea-land combat operations. The Corps land-fired NSM is yet another part of this concept as the Corps is increasing its abiltiy to transit from sea to land for reconnaissance, surveillance and attack operations, movements will will require the transit of Marines from sea to land for land-based weapons set up and land-to-sea-attack. These operations, as expressed in Marine Corps Force Design 2030, will increase the use of unmanned systems and weapons capable of mobile, expeditionary, sea-land operations, able to function in undersea, surface and land combat scenarios. This is quite significant as such an approach is also followed closely by Navy SEALs, and it is a key reason why both units have taken well to the Glock 19. Most of all, however, Spec Ops magazine explains that the Glock 19 is highly tailorable to the operational needs of individual special operators and Marines. “I do believe that most of the special operation guys who make their living with weapons like to tune them to fit exactly the way they want to shoot. Glock with so many aftermarket upgrades like triggers, slides, mag wells, optics, sites, and grip texture allows them to do just that,” Myers writes in Special Ops Magazine.
