What type of encryption devices are used with JREAP A?

The correct choice is based on the specific encryption devices used with the Joint Range Extension Application Protocol (JREAP) A. JREAP A relies on several encryption standards to ensure secure communication over a tactical network, and the KIV-7, KG-84A/C, STE, and OMNI encryption devices are all compatible with this protocol.

The KIV-7 is a fill device that supports multiple types of encrypted voice and data communications, including those required for JREAP A. The KG-84A/C is a legacy encryption device that has been widely used for secure transmission of data. Additionally, the STE (Secure Terminal Equipment) provides a secure communication channel which could be utilized in conjunction with JREAP A. OMNI represents a type of equipment that can handle a broad range of secure communication needs, making it suitable for the diverse requirements of joint operations.

By utilizing these devices, operators ensure that the data being transmitted via JREAP A maintains the necessary levels of security and confidentiality vital to military operations. Thus, the collective use of these encryption options ensures the integrity and security of transmitted information in a military context.
