When was the last time you talked to your Soldiers directly about suicide?

With the recent suicide from famous Comedian/Actor Robin Williams there has been a lot of talk on TV, News, and Radio about the incident. While listening in to a local radio station they were taking callers opinions on the topic. A Soldier called in and openly stated that he has been receiving counseling but implied from his dialogue that he was seriously thinking about taking his life. This sparked a lot of callers to the station offering support to this Soldier. The conversation on the radio station changed to an open discussion on suicide and a group effort help out this one caller.

All it takes is a little bit of help at the right time affect someone's life permanently. So I ask you all, when was the last time you sat down with your team and brought up this topic? If you cannot remember, then it has been too long.
