The fire pods are already in service, have been for awhile, from memory @17 were built for army and airforce replacing the hino rural tenders that were becoming difficult to support. A few deployed to the big fires we went through earlier in the year.Garrison vehicles is moving forwards by parts it seems. The fire pod mounts have been agreed to by type but the details as to how they will be modified is being ironed out. I guessing the success of that may determine the vendor for later orders. But the fire pod trucks are the most urgent.
Currently they are mounted on stripped down unimogs (for weight) but can be easily ISO mounted on MHOV for deployment and will no doubt transfer to the new GATS vehicle in the future once that is finally chosen.
