A quick insert/quick release encryption unit mounting bracket allowing a Type 1 encryption device such as the KIV-7 to be quickly inserted and perhaps more importantly, quickly removed (e.g., in the event of the need for an extremely quick evacuation of a military site). The quick insert/quick release mounting bracket allows for removal of a Type 1 encryption device simply by pulling the encryption unit straight out in the direction of the front of the unit, without the need to physically unscrew or otherwise disconnect individual cable assemblies, or for insertion by simply sliding the encryption unit into place. This facilitates a quick swap out of an encryption unit in the event of failure, or in the event that the sensitive nature of the encryption unit needs to be quickly removed to protect the encryption unit from falling into enemy hands.
