The NH-7 has holes that run through her shoulders, three on the front and three on the back of each. The holes, which are arranged in a circular pattern, two on the top, and one on the bottom, are evenly placed on the imaginary circle, with the lower one oriented in the direction of her arm. These holes are used for interface with mecha and vehicular systems. Inside these holes, you can often see the pink triangle of flesh that surrounds the actual holes themselves.
