Chapter 2 - No Man Left Behind | Intel Data Sniper Guide

You'll find the first laptop (1) in the hut which has a veranda with the sandbagged emplacement with HMG mounted on it.

The second laptop (2) is located slightly off the beaten track you use in this mission. When you're close to the dead bodies of two bad guys lying near the Humvee ahead of bridge (picture #13 and #14 from my walkthrough to this scenario), you should get off the beaten path to the right, and move towards the huts built on stilts - you can see them in the distance, they're on the island behind the "Great Water". You can get to these huts by swimming to them, or by walking a narrow waist which connects this island with the main land. Watch out, in these huts there are three muggers you have to kill, in order to get to the laptop.

The 3rd laptop (3) is located in the last of the fishing villages you visit in this scenario (this village isn't marked on my map, couldn't fit on it). The laptop lies on the table in the shack built on piles near the parked Hummer - there are two terrorists walking on the veranda of this hut. There's also a wreck of some small ship which you can use to orientate yourself when searching the perimeter for this laptop.
