560 Kill Me If You Want

"Captain, Squad 1 down, Squad 1 down. Requesting backup, requesting backup!"

There was a frantic voice coming from the walkie-talkie. The gunshots rang out without end in the forest, shattering the silence, and the leader of Squad 1 was shouting through his walkie-talkie, but then all sounds ceased suddenly. Soon after, he could make out several grunts, and it was clear as day that he had been killed, most likely by having his throats slit.

"Damn it, all of you head toward the area that Squad 1 was combing. Hurry!"

As the whole company's commanding officer, Powell quickly gave out the order then headed toward where Squad 1 had been at top speed.

As soon as that order was given out, there was another voice coming from the walkie-talkie.

"Captain, Squad 2 has been hit. He's too quick, we can't hit him!"

Why was it Squad 2 this time?
