Are Tank Hatches Locked: Security and Operational Strategies

Combat vehicles, such as tanks, incorporate a variety of security measures to protect their crews and maintain operational readiness. One of the critical components in this arsenal is the locking mechanism of tank hatches. These hatches can be locked for both safety and security, but the decision to do so often depends on the tactical situation at hand.

Combat Readiness and Security

In combat situations, tank hatches are frequently secured to protect the crew from enemy fire and chemical agents. This is achieved through locking mechanisms that can be operated from within the tank. These mechanisms ensure that the crew is safe and that the vehicle can be quickly locked down in the event of an attack, minimizing the risk of injuries or fatalities. For example, in the M60 series tanks, the driver and commander hatches are equipped with latching mechanisms that allow them to be secured from the inside. Similarly, the loader's hatch, when occupied, can also be latched from the inside.

Operational Flexibility

During transport or when stationed in a secure area, tank hatches may be locked to prevent unauthorized access. This measure is essential for ensuring the safety and security of the crew and the cargo within the vehicle. However, operational flexibility also requires that the hatches can be easily accessed when necessary. In such cases, simple padlocks are used to ensure that the hatches remain securely closed while still allowing for quick access when needed. If the padlock is lost, cutting off the lock or prying open the driver's hatch with a large hammer or rock is an alternative method to gain access.

Common Locking Mechanisms and Padlocks

While the use of a single padlock is a common means to secure tank hatches, it is important to note that multiple locks are sometimes employed for added security. In some cases, more than one padlock might be used, particularly when the hatch is being locked from the outside. This ensures that even if one lock is compromised, the hatch remains secure. However, the exact number of locks used can vary depending on the specific requirements and the level of security deemed appropriate by the crew or commanding officer.

Real-World Examples and Lessons Learned

During my service as a national guard armor crewman in the early 1980s, it was a standard practice to lock the hatches of the tanks when they were parked or in combat. The M60 series tanks, for instance, had latching mechanisms that allowed the driver, commander, and loader's hatches to be secured from the inside, while a simple padlock was used to secure the loader's hatch when it was not occupied. In situations where the key was lost, cutting off the lock or prying open the driver's hatch became necessary. These experiences highlight the importance of maintaining secure and functional locking mechanisms to ensure the safety and readiness of the crew.

In another scenario, during a battalion exercise, my scout platoon was tasked with being the opposing force (OPFOR). The Blue Force overran our position without spotting us, allowing me to work around behind them and take out the rear M113 gunner. I then opened the rear personnel hatch and fired into the vehicle to finish off the remaining crew. This incident emphasized the critical importance of ensuring that hatches are properly locked and secured to prevent unauthorized access and protect the crew from potential threats.

These real-world experiences underscore the significance of maintaining proper locking mechanisms for tank hatches. While security and operational flexibility are crucial, the ability to quickly and efficiently secure the hatches remains a priority in both training and combat scenarios.
