FORT DRUM, N.Y. (May 31, 2013) -- As the U.S. mission in Afghanistan evolves from full spectrum combat operations to a support role in helping Afghan forces take hold of their country's security, unit commanders emphasize the need for network mobility.Warfighter Information Network-Tactical, or WIN-T, Increment 2, the Army's improved tactical network communications backbone, was designed to fulfill such a mission."As we reduce our presence in Afghanistan, it is absolutely critical that we continue to understand what is happening around us, to understand the operational environment," said Col. Sam Whitehurst, commander of the 3rd Brigade Combat Team, 10th Mountain Division (Light Infantry), during a recent training exercise at Fort Drum, in preparation for his unit's possible deployment to Afghanistan. "My ability to take the information that I am hearing from my team leaders, and then share it with all of our Afghan partners, so they can correspondingly help confirm or deny that information and share what they are seeing, is one of the most critical elements as we go forward into Afghanistan over the next year."The mobile WIN-T Increment 2 network is being fielded as part of the Army's new capability sets. Capability Set 13, or CS 13, is the first of these fully-integrated fielding efforts, which are scalable and tailorable in design to support the changing requirements of current and future missions. CS 13 includes radios, satellite systems, software applications, smartphone-like devices and other network components that provide connectivity from the stationary command post to the commander on-the-move to the dismounted Soldier. WIN-T Increment 2 is the tactical communications network backbone that binds the capability sets together.The Army began fielding CS 13 in October 2012 to 3rd BCT, 10th Mountain Division, which is based at Fort Drum, and to the 4th BCT, 10th Mountain Division, at Fort Polk, La. The two units are training with these advanced capabilities and preparing for possible deployment to Afghanistan with them later this year. The 101st Airborne Division (Air Assault) Headquarters has already been fielded with WIN-T Increment 2 elements, and two BCTs from the 101st are slated for full CS 13 fielding later this year.If called upon to deploy, Army BCTs armed with CS 13 capabilities will serve as Security Forces Advisory and Assist Teams, or SFAATs, who will work with Afghan National Security Forces to improve their capability and help the Afghans secure their country as coalition forces reduce their presence. The coalition forces' footprint continues to decrease and many of the forward operating bases and fixed sites used to access the network are being dismantled.As U.S. forces take down their fixed infrastructure and become more dispersed and mobile in conducting these support operations, they will rely on WIN-T Increment 2 for critical reach-back communications."If you take a look at what we're doing in Afghanistan right now, as U.S. forces start to reduce their presence, we're still partnered with the Afghan National Security Forces and continue to focus on their development, but we're doing it over greater distances," Whitehurst said. "We are distributed throughout the area on a much greater scale than we were before."Having the capability to command and control the brigade on-the-move gives commanders the ability to extend their reach even as the Army reduces its presence. It will enable them to focus on the mission of developing the Afghan Security Forces, Whitehurst said.WIN-T Increment 1, formerly known as the Joint Network Node-Network, began fielding in 2004 and provides Soldiers with high-speed, high-capacity voice, data and video communications down to battalion level units, at-the-quick-halt. It utilizes both satellite and line-of-sight capability for optimum network connectivity and bandwidth efficiency. WIN-T Increment 2 improves upon these technologies by providing Soldiers with an integrated network, which for the first time, provides mobility and reaches down to the company level. It further increases capability by introducing network radios to the architecture and enhancing Network Operations, a suite of integrated monitoring tools used by communications officers to command and control the network.When it comes to combating the communication challenges created by Afghanistan's harsh and expansive terrain, WIN-T Increment 2 provides an advantage over previous capability. It enables communication signals to better reach over mountains and across deserts, said Capt. Jesse Ellis, commander of C company, 3rd Brigade Special Troops Battalion."It is important to be able to communicate quickly and effectively so Soldiers can get the message back and have more support from higher echelons if they need it," Ellis said. "[WIN-T Increment 2] will close the gap in the terrain and the distance, and make things a lot easier for these Soldiers as they become [increasingly] more spread apart."As SFAAT missions evolve, Soldiers will no longer be tied to fixed U.S. bases and secure network infrastructure, so maintaining communications through WIN-T Increment 2 while assisting the Afghans is a "tremendous capability" to bring to the effort, said Maj. Graham Wood, brigade communications officer for 3rd BCT, 10th Mountain Division."It can give a mobile team, such as an SFAAT, the data capability traditionally only available at the brigade and battalion Tactical Operations Centers," Wood said. "Soldiers are not tied to a single point; they can take that upper tier phone and internet capability and can move it wherever they need to go to support their mission."
