Android Thoughts: US Department of Defense Testing Android App for Translation

"The Defense Advanced Research Projects Agency (DARPA), a part of the Department of Defense charged with supplying cutting edge technological options for the entire Department, is currently beta-testing a mobile translation app called Translation System for Tactical Use (TRANSTAC)."

Looks like the United States Department of Defense is utilizing some of Android's apps to aid in communication barriers. Currently, they are beta testing Translation Systems for Tactical Use which allows them to converse back and forth with people speaking other languages. What other apps do you think they may use in the future?
