After completing my latest game, I noticed the "one shot deaths" stat at the end. Since it was right below "one shot kills" I assumed that it was the number of my soldiers that were one-hit-killed by enemies.
However, I had only lost 4 soldiers: 3 in the tutorial mission (I accidentally had it on) and a single MEC trooper in the final mission to a Sectopod. The stat in question said 5.
So it's clear that my assumption of its meaning is incorrect. What is the correct interpretation of this 5?
