I had a teammate (WildBobAA?) tell me the other day that he had sitrep and there was a claymore around the corner I was about to pass around, and the message registered in time for me to quickly pop out in front of it and back to detonate it harmlessly. That kind of teamwork always puts a smile on my face.
...in contrast with me telling a teammate (he was a random obv) that he was about to walk into a claymore recently and him just going ahead and walking into it anyway. Sigh.
