One of the soldiers killed in the "friendly fire incident"was Captain Yonatan Netanel. I know Yonatan's father, Rabbi Amos Netanel quite well. Rabbi Amos is an educator par excellence who teaches/supervises at Talmud Torah Morasha. Below is a letter that Rabbi Amos sent to the parents of his students a couple of days before his son was killed. It tells a lot about the man and his family:
Update: Apparently Yonatan z"l was killed in a different incident than the one I linked to above.
