Do you need to stop frag or SAA?
Its a tanker, not a tank.
Except you need vehicles to operate in the A2 and B echelons (and further back) which at most will be lightly armoured (If even, more likely to be soft skinned (although range of Russian arty??))It's two options. Lightly armoured transport capable of transporting a reasonable load(whatever that is) whilst surviving harassing fire on MSRs or the means of a)preventing the enemy locating said MSRs and b) being capable of smacking the enemy artillery able to reach said MSRs so hard & so fast they don't want to play.
Both need money & long term intent to actually do some real work instead of pissing around on SJAR moments and worrying if an MTP barrack shirt is smart enough.
lightly armoured vehicles to bring the bulk supplies that have been broken up to the F Ech for resupplys (of course that include Zulu vehicles (if suitable))
