There is a special unit in the overall army stucture, which either you volunteer for or you are picked for, but you must agree to enter.
When news of the death of a soldier arrives, the name is NEVER released immediatelly. This is written into LAW.
A group of three, two people from the unit, (one wears a uniform and sometimes the second does not) and a doctor (they cannot come without the doctor) goes to find the family. (Remember sometimes they will just find a sibling or another in the house). They used to go by army jeep, but during war time, Israeli's have this sixth sense for this, the moment the jeep arrived on a street every single person would cower in fear. So now they usually arrive by taxi, with a jeep 5 minutes behind.
The people in the unit obviously have no idea what to expect or what type of reaction they will get. Though they are trained for this, and certainly have too much on-hands training as well. They usually have a complete military file on the person killed.
The family is NEVER left alone. Period. If they need a doctor, for meds or tranquilizers the doctor is there (he is a military doctor). The unit will alwys wait until relatives arrive.
This is done for Jews, Arabs, Druze etc. Each religion, each family, each person obviously reacts differently. Some people actually refuse to open the door, (so that they can delay the news of Job). Some collapse. Some just dont comprehend it. Some become violent. Some stoic, others just fall into a heap into the corner.
But the unit is trained, the names are NEVER released before notification of family, and if the family lives outside of Israel this can take time. The Israieli embassy in the country is contacted and a high-ranking officical coupled with a doctor will be dispatched.
It is to my great sorrow, a very structured thing, based upon too much experience. I know someone in one of these units. Takes him weeks to get his head on straight after he has to do this.
