It does seem to be the direction some of our immediate allies are heading towards, no doubt after lessons learnt, justification and detailed analysis (most likely post Afghan as well), so would make sense to introduce a common calibre across the services via ships, LAV etc especially if we are aqquiring/upgrading the platforms anyway and good time to gain another capability set. Unsure on the differing requirements for "types" of round on the naval vs LAV versions so ammo loadouts could be vastly different anyway negating the "common" round to a degree and still causing seperation as I doubt we would get high end for all purposes.
We do seem to be lacking in the land based anti air department following the mothballing of the mistrals so yes the CAAM (L) could also be another option in the same vein as complimentary land based milleniums. All comes down to perceived gain, requirement and more importantly funding for justification but an interesting concept all the same providing a protective bubble for our troops on the ground as per our ships at sea.
