Not a military strategic blunder, rather a political one.
Also, the equipment that is sent on deployment is, on average, in proper working form. Yes that sounds reasonably ironic considering the report that was just published, but usually shit that is supposed to work, works.
What you could call a military strategic blunder is the four battles of Chora, considering there needed to be four battles to begin with. Thankfully, while mostly fought by Dutch and British/Australian SOF, it was a strategic fuck-up on taskforce level, which wasn't in Dutch hands.
So, equipment-wise, the Battle of Chora wasn't something that left a lot to be desired.
I don't even want to begin about Mali, from the stories I have heard, especially on the leadership level in the Logistics section, it is shit. But again, this is not so much a Dutch blunder as it is a UN one. Fuck me the Dutch government even practically forced the UN to accept Dutch Chinooks and especially apaches into the mission. That shit is usually not-done in a peace-keeping operation, especially with the UN.
Still, the Dutch managed to get it on-board. I guess the UN just wanted Dutch Intel capacity too much for the mission.
