The army fixed the reliability and GPS update times problems, and in 2008, send an infantry battalion (the 4/9th) to Iraq equipped with the "remnants of Land Warrior" gear. The troops found it useful in combat. In particular, they liked how the digital map (they could see in their eyepiece, where it appeared as if they were looking at a laptop display) could be updated by commanders to show new objectives, and how to get there. Since each trooper had GPS and a digital radio, it was easy to send such updates to everyone. This was particularly important because so many operations were at night. Thus the decision to send a brigade (the 5/2nd) equipped with the same gear (eight pounds worth) that the 4/9th battalion found useful.
More on Fifth Brigade of the 2nd Infantry Division here and here.
Just with its larger component of line infantry (3 battalions of 4 companies each, instead of a infantry brigade combat team's normal complement of 2 battalions of 4 companies each), the brigade would be useful in COIN work even without the high tech. And the added numbers may provide a cushion should the technology fail in Afghansitan or be ill-suited to the environment.
