Just to correct you on a few issues.
1-Tanks vs Artillery, Artillery is only truly effective on a stationary target. Because of the distance the round has to travel in the air, with the time of flight it's very very hard to try and calculate where a target will be while moving in order to get artillery rounds onto it. Ditto for rocket batteries.
From what I gather the targeting systems on both pieces are essentially the same. An artillary can be guided by lasers to the target. The same is true for rocket or missile systems.
2-Helo's and Aircraft vs tanks, yep, tank gonna lose. But then again infantry vs. helo or aircraft and us groundpounders are not gonna win that coin toss either, doesn't mean we should get rid of the infantry.
Infantry can hide alot better than a tank can. A good position with cover can launch an RPG and disable a helicopter. I'll give you the aircraft arguement though, but infantry play a vital role in securing structures(though a tank could secure the structure by running over it)
3-In an urban situation tanks are actually quite effective, as long as they have proper infantry support. A tank is a force multiplier, the amount of firepower and protection it brings to the battlefield is unprecedented when compared with other vehicles. The marines in Fallujah learned this when their tanks were taking multiple (sometimes up to 15 in one case) RPG rounds and were still staying in the fight. No tank in the world however can stand up to a TOW or JAVELIN, as those weapon systems are designed to penetrate any armour existing right now. However RPG's which our current enemies around the world use, can be stopped.
Very good point. Perhaps I was thinking alittle ahead because I was considering if the Leos had to fight against more advance launchers. I still think this should be a case because Canada may not always be fighting insurgents or terrorists.
4-LAV's aren't light either, they weight 13+ tons. Does that mean we should leave them at home in favour of going back to using Iltis jeeps which are only about 2,500lbs?
Yes, but you can carry 3 of them and only 1 Leopard. If they are able to do the job, then why wouldn't we go with this?
5-LAV III is about the best APC you can get these days and it's use has been proven time and again in Afghanistan. Doesn't mean we can't improve it, but we do have some awesome equipment. The tank is there as something that can bring that extra punch when required. It's shock and awe against the Taliban cannot be underestimated. They call the LAV III the dragon that sh*ts Canadians, so what would they call the Leo, the super dragon?
Again, there are other things which could bring in that extra punch. Though I will say nothing will ever replace the pyscological fear which a tank brings (maybe mechs

).
With that being said, I have never been in combat, so despite my responses, I'll trust a soldiers word over my opinion anyday. If you guys want the tanks, then you should get tanks.
