The Dutch army actually does have a small tank unit (We literaly have twelve tanks, and not all of them are battle-capable) for training purposses that's integrated in a German armoured batallion. Our mechanized brigade is, in turn, incoorperated within a German armoured division. Germans lack the mobility of our CV90's (Goddamn I love those CV90s) and we lack the firepower of their tanks. We don't have our own tanks because we can rely on our allies as they can rely on us. To think that the Netherlands is going to fight a full conventional war on its own somewhere in the future is completely unrealistic.
That being said, it's not unlikely if we'll see our tank units re-instated. Won't be surprised if they announce Tank Officer School at the KMA before the end of the year, Riddlez. Of course, unless we get a left-wing grand coalition after the election.
Urban warfare without tanks is basically siege warfare as you're incapable of mobile direct-fire artillery (which is the purpose tanks serve in Urban warfare). That, in turn, means you're less able to perform offensive operations and thus less able to surround the enemy. And while tanks are not as effective in downtown-environment with lots of narrow streets and high-rise buildings (Grozny, never forget), they're all the more effective in suburban environments to isolate an enemy.
Tl;dr whatever the situation, having tanks is better then not having tanks.
