Listen my son, and I will tell you much of what I know-
I wouldn't say Israel is deficient in technology, LOL. Actually, if you check on wikipedia, Israel is the foremost leader for its size in military technology and ships out 10% of the world's arms by itself despite being a tiny country.
Some famouse Israeli-invented military tech include the Uzi, the fearsome Merkava MBT series corner-shot SWAT rifle, the IED-protection humvees (being shipped out to our troops in Iraq right now), Israel is actually the only country in the world with an operational anti-ballistic missle defense system, the Hetz, or Arrow, Israel made the Harpy and many other UAV's (the Harpy is currently used in the Afghanistan conflict and the Iraq war by recon units), Israel also has RAFAEL, an advanced armaments company that has developed the SPIKE (a sophisticate guided anti-tank weapon), and the fearsome series of A2A PYTHON missles (said to be good enough to compete with the American make of AMRAAM missles) . Israel also spends a lot (10%) of its GDP on military financing, so they definetely are not deficient in equipment technologies and maintenance.
So we've established Israeli has pretty good technology, mostly domestic made, and some imported by us. But technology doesnt win the war always. We know that in Israel's early days the Arabs had much more equipment, and better equipment, but the Arabs often vastly outgunning and outnumbering the Israelis still managed to lose every war. So how do Israeli's win every war, despite being so outnumbered? One word- guts. Well, actually two words- sheer guts. That and training. My friend's dad was a navy SEAL who once did cross-training with the Israeli commando unit : S-13 (shayetet 13, translation: flotilla 13). He said in his own words : " those guys were the toughest sons of bitches ive ever seen." S-13 is known for its grueling training program, one of the toughest in the world and certainly comparable to the SEALs'hell-week as my friends father told us. I believe much of Israel's skill in battle comes from simple yet effective training. In every war with the Arabs, Israel was at least 65% dependent on reserves- civilians that could be called out to war if needed. They tuned these guys up and got them ready for fighting in about 1-2 days. Israelis are determined fighters, who know their history. They know how the world had so cruelly persecuted their ancestors, and thats another reason. They shine in battle because they want to- they want to tell the world, "you wont ever bother us again, you will never beat us." They are fighting for their home-turf and for their people. The country is so small, they know the risks and consequences for failure-so they work 100 times as hard as anyone to make sure they win, because a war lost for a country so small as Israel could mean disaster. Its determination, bravado, courage, guts, training, spirit.
Its the Israeli army.
