If you were ever actually in a fire fight you wouldn't make such ignorant statements. The Israeli infantry actually use and prefer the FN FAL which is 7.62 mm and the UZI which is 9 mm. Lastly, OBL was never in a fire fight. He uses his weapon as a fashion accessory.
Actually I believe he was, against the Soviets or their puppet Afghan troops, and then later perhaps against everyone else but the Taliban. But against the Soviets and/or Red Afghans for certain.
Not sure he carried that Krinkov then though.
However the Soviets themselves had switched to the 5.45x39 by then. Michail Kalishnikov never liked or approved of the change in cartridge. Of course the change from 7.62x39 to 5.45x39 is not nearly so extreme as going from 7.52 NATO to 5.56 NATO. The 7.62x39 is more akin to the 6.8mm now proposed by some for the M-16 or XM-8.
One of the biggest problems with the M-4 is that the barrel is too short to get the round completely up to speed. I imagine the Krinkov that OBL displays has the same problem.
Everything I've ever read says while the once used the FN/FAL, they now use either the Galil or the M-16. The Galil came/comes in both 7.62 and 5.56, but the 5.56 is more common, except in specialize applications. Every photo I've seen of IDF troops show M-16s and the occasional Galil. The woman troops, and military and civilian police, do carry the UZI. Here's what Wikipedia has to say about Israeli use of the FN/FAL:
The FN FAL saw action in the Suez War (1956), Six Day War (1967) and Yom Kippur War (1973) but received unfavorable reviews by the soldiers who use it. Its main shortage was the inability to carry out full automatic fire and its lack of durability to harsh desert condition. The rifle performed poorly in sandy environment as sand or mud cause it to jam rapidly. The rifle was being replaced during the later stages of the Yom Kippur War when Israeli soldiers replaced for American emergency aid M-16 rifles, and AK-47 assault rifles that were taken from dead and captured Arab soldiers. The Israeli IMI Galil also saw limited action and prove itself highly durable and reliable in the harsh desert conditions of the Sinai and the muddy Golan Heights.
The FN FAL were officially abandoned in 1975, and were replaced by the IMI Galil as the IDF standard issued weapon.
Wikipedia also has articles on the Galil
It's heavy but being somewhat of an AK derivative, reliable. It's also expensive to produce, which is why the Israelis use lots of M-16 variants.
In an interview Uzi Galil said he developed the Galils because of the failure FN-FAls. The 7.62mm was the export version.
