When the aggressor slashes Beth's throat, she instantly dies and falls to the floor. That is not at all how fast a human being or any living creature would die from that type of wound. She would either drown in her own blood, suffocate or die from the massive blood loss, but even though death would follow quickly, it wouldn't be instantaneous.

Ramstein Air Base is actually located west of K-Town (Kaiserslautern), not east.

Additionally, the Air Force does not use MPs. They use Security Forces, who serve the exact same function as MPs.

Even though the lights in the house were simply turned off, when the aggressors finally breach, they search the house using their flashlights instead of simply switching the lights back on.

There were no light switches. Or overhead room lights. When the women went around turning lights off (0:36:10), they were turning off lamps. The bad guys didn't know where all the lamps were, so they couldn't turn them on.

In the final fight between Tess and the leader of the intruders, instead of simply cutting his hand to release her throat and then stabbing him, she allows him to choke her, while stabbing him directly in the chest.

Cutting his hand might not be enough to make him stop, but killing him certainly would.

It is implied early in the movie, that Tess is a recovering alcoholic. However, the beer that she drinks in the end wouldn't technically break her sobriety since it's alcohol free. Notice the white and light blue label specific to the Corona Cero which has 0 alcohol.
