AFV Leading activation questions

[Blackcloud6]

As to this: "I further understand that the spirit of the question is about how tank leader, with no capacity command/activate infantry, can be for said infantry into a situation which would normally require a regular leader to activate them."

Again we must look at the design-for-effect intent.  Here the designer is forcing you, the player/commander/staff to plan your attack and make sure you got the right leaders in the right place.  This is subtle, and great aspect of PG.
