It seems the Palies used an IRA sniper against the Israelis.
Here is a story in a British paper that talks about this tactic..
As The Telegraph disclosed last month, the Israeli intelligence service Mossad asked British security agencies to check on the movements of known IRA killers to help identify a sniper who shot dead seven soldiers and three civilians in 25 minutes - using 25 bullets from a bolt-action rifle.
That would make things even more difficult.
Ugh...replaying John Walsh, who knows nothing about this and should shut up.
