In response to enemy threats in recent years, the Marine Corps supported actively the Navy’s force transformation and mission adjustments. Security Battalions are established under the Air Defense & Base Guard Group, along with an Amphibious Reconnaissance and Patrol Unit, which are tasked respectively with conducting land-based security operations and carrying out maritime security missions using M109 assault boats, to ensure the smooth execution of both land and naval operations.
The Security Battalion under the Air Defense & Base Guard Group of ROCMC was established at the end of last year as part of the force transformation initiative. Its mission is to provide security for land-based mobile missile crews and mobile radar crews, ensuring their mobility throughout the mission and the safety of their positions.
In recent years, the Amphibious Reconnaissance and Patrol Unit has actively adapted its mission in response to enemy threats and the joint force planning directives of Ministry of National Defense (MND). With the Navy’s integration concept, the unit employs M109 assault boats to carry out maritime security missions, ensuring the successful execution of mine-laying operations and the integrity of designated minefields.
Lieutenant Colonel Kuo, commander of the 1st Security Battalion under the Air Defense & Base Guard Group, explained that the battalion’s primary mission is to provide cover and protection for mobile missile and radar crews during their operations, along with route reconnaissance and position security, with most missions conducted using vehicles for mobile escort. Compared to traditional infantry, personnel must be more proficient in vehicle operation and driving, as well as possess basic troubleshooting skills to handle unexpected situations and carry out convoy tactics effectively. In addition, they must be familiar with the equipment used by the mobile crews under protection, so they can take over and complete the mission if there are casualties among escorted personnel.
Lieutenant Colonel Kuo stated that in addition to basic combat skills, the unit regularly conducts scenario-based training to prepare personnel for responding to enemy threats. These responses are tested and validated during readiness patrols conducted by mobile crews, aiming to achieve a combat capability characterized by "rapid response and immediate deployment," thereby ensuring national security.
The First Lieutenant Kang, a leader from the Amphibious Reconnaissance and Patrol Unit, stated that upon receiving a mine-laying security mission order, the unit will quickly assemble and deploy from port to conduct defensive mine-laying escort operations in a standby posture. Throughout the mission, they will provide full escort for mine-laying vessels between the designated minefield and the loading port. At the same time, they will seize opportunities to harass enemy obstacle-clearing ships and aerial threats, aiming to delay their actions, disrupt their attack tempo, and preserve the integrity of the minefield.
The First Lieutenant Kang also noted that the M109 special operations assault boat possesses excellent maneuverability, allowing it to effectively carry out enemy suppression and counter-special forces operations. Its agility enables rapid and appropriate responses to various threat scenarios, ensuring the successful completion of missions assigned by higher command.
Amid escalating enemy threats in recent years, the ROCMC continues to adapt its force structure in line with ongoing transformation efforts, adjusting missions and troop deployment accordingly. Through the Security Battalion under the Air Defense & Base Guard Group and the Amphibious Reconnaissance and Patrol Unit, the Marine Corps carries out both land and maritime security operations. These efforts ensure the safe and effective execution of mobile missile, radar crews, and mine-laying missions. By integrating rapid response and immediate deployment capabilities, the Marine Corps are ready to defend coastal waters and safeguard national security.
