AT fire in assault hexes

[cjsiam]

Did we summarize this then?

AT fire, within an "Assault hex" (that being one with units of both sides) is allowed against vehicles inside said hex, and does NOT instigate an assault.

Tanks are only obligated to use ASSAULT combat if they are moving into a non-"Assault hex" (no friendly units were in the hex at the start of that activation segment)
...at that point they must do an ASSAULT combat
....if they move in later, or stay multiple turns, they may choose to attack or not, and may use AT in hex(via activation) or ASSAULT(offensively or defensively) if they do.

At no time does an ASSAULT combat, either offensively or defensively, involve or instigate any AT Fire.  AT Fire requires an activation independent of the ASSAULT, offensively or defensively.

This also means that if an AT gun is in a trench, or town---and a tank moves in---it only gets to opportunity fire IF there is no other enemy units in the hex at the
moment(can't fire out of Assault hex) of approach of the tanks....Thus, AT guns would never use their AT firepower in an assault hex defensively in ASSAULT, only
through activation to fire AT.

I think that's where we end up.
