Still seems like a waste to me, probably more an effort to raise funds rather than any specific purpose. I still beleive if anything they should have the turrets removed and serve new roles in a support capacity such as ambulance, C2, driver training, mortars, spec trades etc. You can never have too many supporties under armour.
Even the turrets could be re-used, static mount at the range for basic training, maintanence trainers, mount on a armoured container for deployable base defence or even stick them on the navy IPVs.
The more armoured platforms you can save now mean less needed in the future, granted they may not be suitable for all applications but if we get next to nothing for them then may as well make the best of them.
