ZombieMod takes a unique approach on the Zombie Apocalypse by putting it in the perspective of a military commander, not a survivor. Since it is 2 years after the first infections, resistance on the east coast is organized, resulting in battles rather than small groups fighting for survival.
One of the issues faced by adding city maps is the fact that airstrikes don't look particularly good, so to compensate for this, the International Crisis doctrine will have one of its airstrike abilities replaced by a Leopard 2a6 from the Canadian Army. It will function similarly to the Abrams.

will the leopard be a solo tank or will you be able to get more then one like normal production
One at a time, just like the Abrams. It's tough enough to kill one! However the M60 will probably be set up so you can call 2 in at a time, since it is weaker than the newer tanks.
Will you add the British Challenger 2?
No. There's no reason to have it.
Can we get a squad of Canadian Rifles to go with it? Tanks should never be sent unsupported. (Especially against zombies).
Canadians are included in the form of JTF2 as part of the foreign infantry call in.
How can the zombies destroy a tank, considering (typically) zombies are unable to use anti-tank weaponry?
As I said on a similar comment on the M60, currently all zombies will do very small amounts of damage to vehicles. There are special zombies that do large amounts.
