Looking through some old DARPA budget docs[1], it seems like there's a chance that what's being discussed here falls under DARPA's "PE 0602702E TACTICAL TECHNOLOGY" initiative, project TT-06.

Some other possibilities might include:

  - "PE 0602304E COGNITIVE COMPUTING SYSTEMS", project COG-02.
  - "PE 0602716E ELECTRONICS TECHNOLOGY", project ELT-01
  - "PE 0603760E COMMAND, CONTROL AND COMMUNICATIONS SYSTEMS", project CCC-02
  - "PE 0603766E NETWORK-CENTRIC WARFARE TECHNOLOGY", project NET-01
  - "PE 0603767E SENSOR TECHNOLOGY", project SEN-02
