1. Purpose. To provide procedural guidance for controlling outgoing
communications and network paths for 15th Marine Expeditionary Unit (MEU)
from the USS PELELIU (LHA-5) for the purpose of operations security (OPSEC)
and force protection.
2. Background. RIVER CITY conditions are used as a countermeasure to
prevent the release of sensitive information – Essential Elements of Friendly
Information (EEFI) — by controlling outgoing communications and network paths

administrative or personal use).

that reduces incoming traffic during military operations and/or threats to
the computer network.
b. EEFI are those elements of information that are particularly
vulnerable to adversary exploitation, and requires protection.
c. RIVER CITY conditions should be employed prior to setting certain
force protection conditions, commencing sensitive mission planning, and/or
operations that could be compromised by an inadvertent communications or
d. Instances where RIVER CITY may be required include, but are not
limited to: special operations support, strait transits, offensive strikes,
response to casualties, high-tempo operations, or when web browsing is
adversely affecting the command’s operational mission. Additionally, RIVER
CITY will be set in response to serious events, or as the Information Warfare
Commander (IWC), deems necessary to control transmitted information by phone
or electronic mail.
