Dude, the guy you are replying to is a retard. He thinks india is a stronger military power than China :/
Forget him.
Regarding Arjun II....Pakistan's upgraded Al Khalid-1 tank already matches Arjun II...
When Arjun II came out, indian forums were buzzing and everyone was happy. So one day, I was reading discussions on Arjun II and indians were going "OMG..it has thermal imagers...OMG, it has BMS and it commander can control UAVs from within..it is this and that and blah blah" ...and after reading for a while..I was like "Wait! Al Khalid-I already has all of them..how is Arjun II superior then?" Then I realized that actually, Pakistan might not even need to bring out its Al Khalid II..since Al Khalid-I pretty much matches Arjun II already
So here is a basic comparison between the two tanks...
Note : highlight = Advantage over the other tank
No highlight means can't say if an advantage or not. Since different things have different uses.
Weight
Al Khalid-1 : 48 tons
Merkava IV : 68 tons.
Speed
Al Khalid-1 : 72 km/h
Arjun II : 58 km/h
Main Armament
Al Khalid-1 : 125 mm smooth bore gun
Arjun II : 120 mm
rifled gun
Payload Capacity
Al Khalid-1 : 49 rounds
Arjun II : 39 rounds
Engine
Al Khalid-1 : KMDB 6TD-2 6-cylinder diesel 1,200 hp (with upgrade)
Arjun II : 10 cylinder, V-90 turbo charged 1400 hp
Power/Weight ratio (critical for superior accelaration)
Al Khalid-1 : 26 hp/tonne
Arjun II : 20.1 hp/tonne
Armour
Al Khalid-1 : Composite armour, and RHA, with ERA plate coating (right up there. very tough)
Arjun II : Improved kanchan armour, Russian-style ERA (slightly better)
Operational Range
Al Khalid-1 : 500 km
Arjun II : 450 km
Protection
Al Khalid-1 : VARTA active protection system
Arjun II : ???
ATGMs
Al Khalid-1 : Kombat , 9M119 Refleks (AT-11 Sniper) etc (laser beam guidance, unstoppable since can't be detected due to laser beam guidance method..some claim it also has top attack mode. Unsure about it though)
Arjun II : LAHAT (Top attack mode..very effective!)
Types of rounds carried
Al Khalid-I: APFSDS, HEAT-FS , HE-FS, Depleted Uranium rounds and KOMBAT ATGM
Arjun II: FSAPDS, HESH, PCB, TB, and Lahat ATGM
Other than this, both Al Khalid-I and Arjun II have thermal imagers, panoramic sites for commanders, and Battlefield management systems...
Al Khalid-1's muzzle velocity is very damn good too...superior to that of even Merkava IV...but I didn't get stats for Arjun II muzzle velocity or rate of fire..so can't say anything...
Conclusion: Al Khalid-1 is right up there, if not superior, to Arjun II. Arjun sure has its advantages in heavier armour..but then Al Khalid-1 is superior to Arjun in mobility, speed, and firepower...
Pakistan's Al Khalid project is by all measures superior to indian arjun..
Remember, Al Khalid-II is coming out in December at IDEAS 2014 and it will have better armour than current Al Khalid-1 tank.
