We live in the booming information age, where information of all sorts is readily accessible to countless people across the globe. Videos, articles and social media posts can be shared and viewed like never before — everything from cute cat videos in rural Japan to gruesome decapitations in Syria to wildfires in western America — it’s all there.

How does this affect the world of combat?

Of course, there are the obvious ones. Alex Hollings covers one such instance in his cleverly named article, “Loose apps set traps,” where U.S. service members were incidentally mapping out their Forward Operating Base (FOB) using fitness trackers. This is a perfect example of a clear breach of OPSEC. Recording and uploading tactical procedures or troop positions would be another example — in the 1940s, soldiers were in no danger of having video recorded of their position and that video getting sent to the enemy within minutes. Any effort like that would have taken considerable resources; now it just takes the phone that’s in everyone’s pockets and some signal.

However, there are less blatant uses of video and the spreading of information that can negatively affect OPSEC. Taking pictures and uploading them of a cool helicopter someone saw overseas, or simply texting someone and telling them when you’re coming home — these can have devastating effects, and they have in the past. The problem with these seemingly “innocent” breaches of OPSEC, is that it probably won’t have much effect. Still, it’s the one time that gets you, and it’s almost always something “innocent” that gets people in trouble.
