Sort of, but there's an important exception... ...that I'm not certain i understand!
Here's a Q&A:
C6.52
...
For example, if a unit moves into a location with an ½" acquisition counter and subsequently advances out of the location without being fired upon by the gun that has the location acquired, can/must that advancing unit be tracked?
A. It cannot, unless by moving into the location it became part of a stack that was acquired.
So... when does something become "part of a stack"? Suppose a hex contains a unit X which was acquired by a Gun. X's Mph is over. Unit Y moves thru X's location. Is it part of the stack and can 'pick up' the acquisition'? There is no definition of stack in the index. Must a unit spend simultaneous MF/MP to be part of a stack... must it begin/end a phase in the same location? Or must it simply occupy the same location as another unit to constitute a stack? -- the phrasing of the Q&A "unless by moving into the location it became part of a stack that was acquired" suggests to me that all that is required is moving into the stack location. Help appreciated.
