According to Boxer (armoured fighting vehicle) - Wikipedia
" 200 vehicles, deliveries from 2013 until 2018. The last Dutch Boxer was produced in July 2018. Variant breakdown following a 2016 contract modification was 12 cargo, 92 engineer (subsequently converted 12 of the 92 to Battle Damage Repair (BDR) configuration), 36 command post, 8 driver training, 52 ambulance. "
So there are no indications that the KL will add more Boxers.
Same case with the Leopard 2A6: since 2012 the Netherlands do not posses any tanks, until now, so nothing will change.
De Leopard 2A6 is een zware gevechtstank bedoeld om bij een aanval, vertraging of verdediging overwicht te creëren op het slagveld. Dit 60 ton wegende monster is het krachtigste wapensysteem van de landmacht. Nederland least 18 gemoderniseerde tanks van Duitsland.
last week I had the opportunity to join the Dutch 11th Air mobile Brigade during a patrol exercise. Really nice to see these guys in action. The LMB (Air Assault) is the most offensive weapon of the Royal Netherlands Army. They are specialized in quick response and are mostly one o f the first military forces which are forwarded in enemy terrain during actions. In the recent years this Brigade became part of the German Division Schnelle Krafte which is the German version of an Air Mobile Division. the corporation between Germany and the Netherlands is integrated on a joined unit specialized in these kinds of assault actions. See in the link here video of these soldiers in action on the heath somewhere in the Netherlands!
