Ashkan,
You'd be surprised actually. A huge chunk of our budget goes towards personnel costs - not just salary, but extra pay for deployments, operations, various pay entitlements depending on where you are, cost of living, helping members move from one base to another, helping to pay for their post secondary educations, education reimbursements, reimbursement for members who have to travel X kilometers to work if they happen to be in remote areas. It adds up.
We also have forces deployed around the world, which Turkey does not. Military aircraft can be assisting in Europe, or over the Middle East, or participating in exercises like RIMPAC. Sometimes all 3 at once. Ditto for the Navy, having a few ships out in various parts of the world on various exercises & operations. (Increase costs of personnel, plus fuel, maintenance, accommodations, etc)
That being said, I do agree with you. I don't think anybody on these forums will argue with you that we don't get the most bang for our buck when it comes to equipment purchases...and that's far more of a political-process problem than a DND problem.
^^ Best to continue that topic in another thread. Plenty already exist where we discuss the various organizational shortcomings of the CF/DND. Lets keep this on track regarding Western artillery capabilities.
