I've laughed at, "Military Intelligence" ever since it sent a squad to rescue a downed Arc Light crew (part of Operation Linebacker II) . The squad was suppose to use "HI" (Harassment and Interdiction) tactics to keep the enemy distracted so a rescue helo could extract them.
The Military Intelligence said there was only a platoon of NVA in the area. Well, Military Intelligence was off just a wee bit, there was almost a frigging battalion! Estimates of around 500 NVA, so over two full companies at the least!.....
