The approach precedes the attack. It has to and Green-on-Blue attacks are no different. An attacker must get closer to his target in order to be successful, but it also is going to cause that person to stand out from the baseline. If you are a new reader, I recommend you take a look at the article explaining Proxemic Pulls to better understand this dynamic before moving on:
From Science To The Streets – Where The Proxemic Pull Came From
The reason for this is that attackers intuitively understand the principle that Proximity Negates Skill. If you can’t shoot someone from 500 yards away, you have to get within a range where you can hit your target. If you don’t have a gun, you need to get within knife striking range. If you don’t the skill or the ability, you have to get within a closer proximity to compensate and be successful.
The consequences for failing to identify an insider threat are extremely high, and while the fact that attackers are moving closer to Marines or Soldiers can make stopping these attacks more challenging (a closer attacker reduces the amount of time available to react and limits the number of options available for dealing with the threat), it also simplifies the problem as well.
