SIR (Regimental Information System) is the French Army's tactical C2
system, designed to support joint air/land operations. The heart of
the battlefield digitization, SIR supports command and control
functions at the battle-group, battalion, and squadron and company
level. Two versions of the system are available – shelter-based module
and vehicular version, installed in command vehicles (VAB) for
deployed and on-the-move operations.
Implementation of SIR is expected to add a force multiplier to current
army formations, improve response time, through optimized planning and
rapid execution of combined arms air/land operations, with improved
logistics and support.
The system is supported by integrated communications suite, based on
the standard French Army radios - Thales PR4G tactical communications
sets. Command and Control applications developed for SIR utilize
map-based situational displays, integrated mission planning tools;
order preparation templates, coordination and synchronization tools.
SIR is designed for multinational operation, through interoperability
with other NATO C4 systems through the Multilateral Interoperability
Program (MIP) standard. Subsets of SIR were designed for unique uses,
including order of battle administration, NBC, meteorology. Other
branch specific derivatives were adapted for armor, infantry army
aviation, engineering corps and logistics units.
Situated at the Brigade/Regimental level, SIR is integrated with
higher command levels through the SICF information systems, while
connectivity to the lower combat formations is routed through the SIT
(Finders) battle management systems, used at battalion level and
below. SIR shares information and connectivity with branch specific C2
systems including Atlas divisional artillery C2, Martha army aviation
C2, SEGA and RITA area communications systems.
The vehicular command posts (VPC) are based on three main subsystems –
communications - including radios, communications servers and routers.
The processing platform includes the local area network and
workstations, with associated software. The third element is the
interfaces that integrate the two modules into the vehicular system.
In a common deployment, two VPCs are combined to operate a regimental
command post. Up to six vehicles can be integrated to support more
complex task force. At present, SIR uses the data communications
services provided by standard VHF PR4G Combat Net Radios. Data over HF
can also be supported via gateway to the Carthage HF radio set. Future
links will support PR4G VS4 as well as over the next generation IP
based 4th Generation RITA military wide area subscriber communications
network.
