That's what I was getting at gwyidion.
Whilst skinnedpuppy is obviously correct that the two AD systems I mentioned are MANPADS, the term ‘Infantry’ has a specific meaning within the game mechanics i.e. infantry is what the table on p. 52 and the ‘Arm’ column of an army list say it is. Indeed, the table recognises this when it specifically prevents infantry support units from being carried by IFVs, although they are themselves classed as ‘Infantry’. I have no quibble with this.
What I was asking was; are there any other exceptions (I can’t find any) and could a reasonable case be made to allow other units, currently prohibited, to be carried in an IFV. One for the TO&E wizards…
