The Army began fielding the Warfighter Information Network – Tactical (WIN-T) Increment 1, formerly known as the “Joint Network Node Network,” in 2004 and completed fielding in 2012 to all units dedicated to receive the capability.

The WIN-T Increment 1 End Of Life Technical Refresh effort currently underway is one of four upgrades being made to WIN-T Increment 1. This effort advances capability while reducing equipment by one-third for increased unit agility. An ongoing enhanced networking upgrade, the WIN-T Increment 1B upgrade improves the efficiency, security and interoperability of the network. Other upgrades include the Network Operations Convergence Upgrade that simplifies and reduces the number of network management tools communications officers (S6s and G6s) use to manage the tactical communications network, and the High Capacity Line Of Sight Radio Upgrade that provides more than a fourfold increase in throughput.


Similar to a home Internet connection, WIN-T Increment 1 provides a full range of at-the-halt data, voice and video communications, allowing Soldiers to simply pull over to the side of the road to communicate. WIN-T Increment 1 provides this networking capability to command posts and units at the battalion level and above.
