Anyone else been getting magically killed from behind by an axe at helmand valley in MOH for ps3?

In 2 different matches yesterday,and one today on combat mission at helmand valley I was seemingly magically axe murdered from behind 5 times in 1 match.The 4th time I was facing the enemy and would have seen anyone come up.The 5th time I went back to that same area,cleared it,there was def nobody there,and again it happened.The one time tonight when it happened,I was way back in the spawn area,too far for any enemy to be able to go without dropping dead from going out of bounds.
