Mission Network


Integrated into the Army’s holistic tactical communications network, Warfighter Information Network-Tactical (WIN-T) Increment 2 provides interoperable mobile network connectivity to deliver dynamic networking operations to the entire battle space. The system provides robust on-the-move mission command capability enabled by a mobile network communications infrastructure employing military and commercial satellite connectivity and line-of-sight radios and antennas.

Combat vehicles integrated with WIN-T Increment 2 provide the on-the-move communications, mission command and situational awareness that commanders need to lead from anywhere on the battlefield.  WIN-T Increment 2 enables operations down to the company level in remote and challenging terrain while maintaining voice, video and data communications connectivity rivaling that found in a stationary command post.  With WIN-T Increment 2, Soldiers can utilize applications for maneuver, fires and intelligence from inside vehicles, enabling commanders to make decisions on-the-move rather than being tied down to a fixed command post. This capability ensures effective and less predictable offensive and defensive operations. In the fires battalions, the system improves the speed and reliability of the fires network while also extending range and increasing the survivability of artillery units.

In support of expeditionary, quick reaction and Air Assault missions, the Army is providing lighter weight, more transportable alternatives to the current Tactical Communications Node (TCN) and Network Operations (NetOps) and Security Center (NOSC). The new configurations provide the same support to commands posts and on-the-move operations as the current configurations but are integrated onto sling-loadable HMMWV platforms.

WIN-T Increment 2 began fielding in October 2012. The Army will continue to provide the proven capability of WIN-T Increment 1 where unit requirements can be satisfied with at-the-halt networking capability.  But those units where mobility is critical to mission success will receive WIN-T Increment 2.

Main Components

  • The Tactical Communications Node (TCN) provides the principal backbone element and supports command post operations for the WIN-T Increment 2 network. The TCN provides communication and networking equipment and allows the Soldier the ability to access the network at a variety of security levels. While at-the-halt, the TCN is equipped with a 10 meter, extendable mast to improve line-of-sight connectivity and larger satellite assemblage for high throughput.
  • The Point of Presence (PoP) is installed on select combat platforms at division, brigade and battalion echelons, enabling mobile mission command by providing on-the-move network connectivity, both line-of-sight and beyond-line-of-sight.
  • The Soldier Network Extension (SNE) is installed on select vehicles to provide on-the-move network communications to extend the network from the brigade down to the company level. Using its on-the-move satellite communication systems, the SNE can also be used to heal and extend lower echelon tactical radio networks for geographically separated elements blocked by terrain features.
  • The Vehicle Wireless Package (VWP) is a communications package for non-WIN-T Command and Control (C2) vehicles. The VWP B-Kit provides remote connectivity to a TCN via a Local Access Waveform for command and control vehicles during at-the-halt and on-the-move operations. It is a small form factor Local Area Network extension of the TCN’s satellite and terrestrial line-of-sight network systems.
  • The Network Operations (NetOps) and Security Center (NOSC) provides network management and enhanced tactical network planning, administration, monitoring and response capabilities. The hardware is located on the vehicle and is connected by cables to the laptops and large display screens inside the tactical operations center where the communications officers manage the network.
  • The Satellite Transportable Terminal Plus (STT+), a trailer-mounted ground satellite communications terminal with a generator, is used in conjunction with the TCN at the halt to provide relatively high throughput satellite communications.
