The turret rear of the Merkava poses a nasty shot trap. The
chains are designed to kill the fuzes of HEAT type charges.
The Merkava is fairly well armored even if it doesn't used
Chobbam type sandwiched stuff relying mainly on cast surfaces and plates;
spaced armor. Case in point the hullfront/glacis plate has four layers
of armor with some spaces acting as fuel tanks.
The engine on the Mark3 does give the tank a little bit more pep
than its predecessors- a 1200hp General Dynamics/Teledyne Continental
variable compression V12- with an Israeli Ashot hydrokinetic automatic
transmission (compared to the 900 hp V12 on the Mk1 and Mk2) still the
Merkava's slower than other Western ueberpanzers also due to its
suspensions unlike going for a advanced torsion bar setup with rotary
shock absorbers found on the Leo2s and M1s or the indpendently mounted
hydropneumatic/hydraulic shock suspension found on the Challengers the
Merkavas use the Horstman heavy spring/bogie pair type suspension found
on most British tranks since World War Two.

Nope. the Israelis still like the concept of four men tanks.
Aside form the eight or so rounds stowed vertically in the turret (below
the turret ring) nearly all 50 or so rounds carried by the Mk.3 Merkava
is stwoed in the hull rear. That means the loader's going to have to get
off his butt crawl down and start picking up 120 rounds.
I'm suprised the IDF/A decided to go with the Rheinmetall 120/44
smoothbore considering every one of their tanks are armed with the
M68/M68E1/A1 105 guns. Israeli 120 ammo performance specs haven't been
availiable but me guess is that they're doing a good deal of reasearch on
long rod type sabot rounds possibly even switching to DU.
The Mk.3 does have a thermal imager and a laser rangefinder plus
supposedly (or planned) handoff hunter killer type sight for the TC. And
Yes there's still a 2000 round hopper for the 7.62mm coax and a roof
mounted Soltam 60mm mortar to launch smoke/WP and HE rounds plus TC and
