    Reaching a protection level similar to the Leopard 1A1A1 ?

    Development of a 8-tonne reconnaissance amphibious tracked vehicle (ERAC) was launched in 1960. The use of a fin-stabilized shaped charge projectile as main anti-tank round was deemed obvious given the performance achieved with the 90 mm shell. The project consists of a D 739 gun firing a 105 mm projectile with a steel body designed to be fired under higher pressure (2100 kg/cm²) with a muzzle velocity of 850 m/s. The static firing trials in 1962 and the ERAC prototype the following year fall short of expectations ; the accuracy is barely acceptable and the armor penetration is mediocre compared to the caliber. Meanwhile, the ERAC project is cancelled and its successor, the ECA (Engin de Combat Amphibie : amphibious fighting machine) didn't have any more luck. The AMX-10 RC also used a fin-stabilized shaped charge projectile but with a superior ballistic performance (1100 m/s). - MAREST, M, TAUZIN, M, COMHART T9 ; L'armement de gros calibre, Centre des hautes études de l’armement Division Histoire, Paris, 2008.

    What are the purpose of the two holes ahead of the right exhaust ? APU exhaust, CBRN filtration system, air conditioning, ... ?

    The protection is focused on the crew survival cell, everything else around it is expendable.

    AFAIK, the Spanish used the OE mod. 60 and the OCC 105 F1 rounds on their Pattons.

    The French BS G2 ERA brick is also effective against kinetic energy projectiles (Jane's International Defense Review, Volume No. 29, May 1996, p.17) :

    This is quite logical, the 90 mm gun was shorter (L/40.4) versus L/52.5 for the M47 and M48. However, the original requirements stated that the gun tube had to be ballistically on the same high level as that of the 90 mm M41 rifled gun. Thus, the same 90 mm ammunition as in service with the M47 and M48 MBTs could be fired. The strength of the metal used for the gun (also called Rheinmetall BK 90 ?) was planned to incorporate the development of future higher performance ammunition. Only HEAT-T and HESH-T ammunition are mentionned in the specific literature.

    ERAC 120 assault gun concept from 1985 : ERAC stands for Engin de Réaction Anti-Chars à canon de 120 mm (anti-tank reactive machine with 120 mm gun), it was designed by the ETAS, a small design bureau of Angers, which, at the time doesn't relied on Computer-Aided Design. The ERAC 120 assault gun was intended for mechanized infantry units, providing them an unmatched heavy fire support. The planned combat weight of this assault gun was around 30 metric tons, it was to be powered by a Baudouin six-cylinder 700 hp diesel engine coupled to an automatic gearbox featuring an infinitely variable, power shunt, hydrostatic steering system. To reduce the infrared signature, the cooling system (two ring-type radiators) was located at the rear of the hull. The running gear itself consisted of six road wheels on either side of the hull. The five road wheels option was rejected due to the hull's pitching motion. The ERAC 120 used double-pin tracks and hydropneumatic suspensions. The gun was a shortened version (L/44) of the Giat CN120-26 (Modèle F1) 120 mm smoothbore gun fed by a twelve-round continuous link carrier autoloader. The autoloader could be replenished under armor by a fifteen-round open-chain magazine through a ceiling-mounted clamp. Elevation was from +15° to -6° while traverse extended to 8° on either side. The 7.62 mm remote weapon station was reminiscent of the ATO RWS of the tropicalized Leclerc. Regarding the armor, it has been estimated that it reliably met the STANAG level 5 protection level. The drawings below also show the three-man configuration (a four-man concept was also envisaged but it was taller and thus heavier) : Credits : Marc Chassillan's article in the special edition No. 73 of Raids magazine.

    Does the T-90M retains all features of the T-90MS or some of them have been omitted for cost saving reasons ? Source ?

    Regarding the presence of composite armor in the hull of the Mk. 3 (the production Block is not specified) : And also inside the double bottom. According to Marc Chassillan, the two fuel tanks at the back of the Merkava Mk. 3 can be purged through dump valves. In real life, there are only 4 rounds (in their fireproof canisters) between the turret basket and the engine bulkhead. The number of rounds carried in the aft compartment is also incorrect :

    Michael Jerchel names the TEM-1A rangefinder sight and TRP-1A and TRP-2A commander's panoramic sights while Stefan Kotsch also mentions the TRP-5 and the CIA comes with this : So, who is right ?
