It's built on an old M-60 chasis...Israel refined the turret and fire control system, some have added armor...though a good tank, it's out of date by our standards...
We should give the Israelies some M-1A2s.
Assume it doesn't have reactive armor?
Also, it looks like the Hezbos got some of the new top attack AT missiles from Russia(via Iran and Syria) or they have modified their tactics to attack the Merkava at it's weak points. The M1A2 has better ceramic armor, fire suppression, and armor on the top that would defeat most of these types of attacks.
'We should give the Israelies some M-1A2s.'
No, the brits should sell them some Challenger 2's - the best armoured tank in NATO. The M1A2 uses the original British Chobham armour which is very good, but the Challenger 2 uses 2nd generation chobham which is even better. If someones shooting at you, you want to be in a Challenger!

Dare we say it? Without proper tactics, tanks are a diminishing asset.
I think you are mistaken...the Magach is designed off of the M-60 chasis, the Merkava was a all new design.
I don't think it is based on the M-60. Note that the drive sprocket and the final drives are at the FRONT and not the rear of the vehicle. In the M60 the power train is a complete package at the rear of the vehicle. A driveshaft from the rear to the front would raise the profile ala the Sherman. Also the Merekva has a troop carrying compartment at the rear of the vehicle, which rules out a powertrain there. I think the Merkeva was a ground up engineered Israeli invention, as a result of their having to rely on US replacement for tank losses during the Yom Kippur war amid strong Congressional opposition. The Israeli's did up engineer a number of M60's untill they acquired sufficient Merkevas.
I was a tank commander in the Vietnam war, and I worked on many M60's (we used M48A3's in Nam) in the States and in Europe.
