WIN-T Increment 2


Warfighter Information Network-Tactical (WIN-T) Increment 2 provides an integrated tactical network leveraging proven commercial and government technology. It provides on-the-move capability and a mobile infrastructure by employing military and commercial satellite connectivity and line-of-sight (terrestrial) radios and antennas to achieve end-to-end connectivity and dynamic networking operations. WIN-T Increment 2 extends the network to company level for maneuver brigades for the first time.


The tactical network remains a high modernization priority for the Army. WIN-T Increment 2 supports operations while on-the-move and pushes that integrated on-the-move capability down to the company level for the first time. It also introduces networking radios and enhances Network Operations (NetOps) for network planning and monitoring. Tactical Communication Nodes (TCNs) in WIN-T Increment 2 are the first step to providing a mobile infrastructure on the battlefield. When the TCNs are combined with the Points of Presence, Vehicle Wireless Packages and Soldier Network Extensions, WIN-T Increment 2 enables mobile mission command from division to company in a mobile, ad-hoc, self-forming, self-healing network. WIN-T Increment 2 embeds secure communications equipment into select combat vehicles, giving WIN-T Increment 2 -equipped units the ability to maneuver on the battlefield and maintain connectivity to the network to ensure situational awareness and maintain command and control of forces. 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 and ensuring effective and unpredictable offensive and defensive operations.

WIN-T Increment 2 began fielding in October 2012 and is fielded as the tactical network communications backbone of the Army’s capability sets. Going forward, unit requirements that can be satisfied with at-the-halt networking capability will remain with WIN-T Increment 1, while those units where mobility is critical to mission success will receive WIN-T Increment 2.

Main Concepts

  • The Tactical Communications Node (TCN) provides the principal backbone element and supports command post operations for the WIN-T Increment 2 network. It 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 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 at the company echelon to extend the network from the brigade down to the company level for the first time. Using its on-the-move satellite communication systems, the SNE will 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.
