Them 20 LAVs are still sitting in storage at Trentham waiting for a buyer. Seems that NZG is having a problem offloading them. Maybe they should suck the prune and refigure them for another role, such as ambos etc.
For Sale: Defence vehicles sit idle waiting for a buyer
I think even minus those 20 QAMR still has the numbers, including enough for the other roles already as compared to the old M113 fleet of @70 (in which we had ambos, fitters, mortars etc) so a fleet of 85 NZLAV should in theory suffice if we have indeed reverted back to the battlefeild taxi days and Sqn org of old. Numbers for these extra roles would not be big ie say 3 ambos, 4 mortars so no massive increase and some roles are already incorporated such as HQ, FO, recon etc.
At the moment I think they have @20 hulls in each sqn plus HQ and recon so actual QA would have @ 50 LAV. Combat school also has a few plus workshops and a few others so in reality they can re-role within the numbers they have (use) so I guess it more comes down to re-engineering these hulls into the dedicated roles from the base model.
Perhaps a re-established FSV variant in the fire support role could be added as you say but apparently the 25mm cannon on every vehicle was the trade off for the loss of the scorpions fire power so the peaceniks will pull that angle. As you say though if the vehicles are just sitting there gathering cobwebs, getting older and de-valueing anyway then we may as well put them to use so why not although I think one of the original problems was, like navy, a crewing issue as in getting/having/keeping enough qualified crew to keep the wheels turning on the larger more technical fleet.
@Massive Just going off our penchant for holding onto equipment well past used by date and given NZLAVs relative "youth" coupled with our trouble to even sell 20 nevermind 105 I think a MLU would/should be the call. Tagging our fleet onto the end of Canadas LAV6.0 programme and line would be the less risky option whilst still affording us tangible benefits for the future fleet, obviously with NZ specific requirements, be that good or bad (ie more or less). Knowing our politicians could range anywhere from a full upgraded firepower and driveline package to minimal new set of tyres and a fresh lick of paint and voila, new and improved.
Boxer is also a larger beast than even our current LAV so if we did not use NZLAV in afghan (arguably our most oppourtune mission to do so) for so long due to terrain, size, complexity etc would going "bigger and better" actually be a plus or a minus realistically for what we do going off historic ops? Plusses and minuses for us I would suspect.
