An interesting study on unit discipline and behaviour towards the local population. I'm afraid I don't have access to the original, however, so this is a report on a report on a report

I must say, however, that it doesn't entirely square with what I've heard from many Palestinians, namely that older reservists are less likely to engage in brutality or humiliation than younger IDF conscripts. The study seems to have used Palestinian complaints as its indicator--which, given how very, very rarely Palestinians would bother complaining to the IDF, may be a rather suspect measure...

Study: Sloppy soldiers more violent against Palestinians - length of tour
not factor

Dr. Aaron Lerner Date: 22 March, 2008

Correspondent Chagai Huberman reports in the 18 March edition of Makor
Rishon that a study by the Behavioral Studies Department of the IDF of over
a thousand soldiers who served in the West Bank found no correlation between
the length of duty and the propensity for a complaint to be made against
them for violence against Palestinians.

The study did find a strong correlation between the sloppiness of units (for
example gear missing/not guarded properly) and their propensity to get
complaints about violence against Palestinians.
