We just had a little battle clearing out one of the nodes in the train map. I was running my sentinel (assault HMG on it), and had just finished clearing out the building there of its red infestation.
After another red just about spawned on my head, I thought "oh ****, that's right, they have a ground spawn here", killed said red, and got the **** out just in time to see the node get over-run by reds coming from the objective for some reason.

So I hacked the nearby railgun installation, took a few potshots at the few that decided to follow me, and lost track of the last one. In order to stop myself from getting jumped, I ran into the nearby pillbox.
Turned out it was a logi, and they seemed to think I was an idiot, because they kept throwing down REs at the entrance, and I kept destroying them. I was even close to enough to hear it every time he threw one down.

Just as I was satisfied there were no RE's left, and the logi apparently tried circling around to the window of the pillbox, the match ended.

This was just earlier today.

And I was waiting by the door/window with my HMG waiting for him to give me something to shoot.
