Transported Spotter

I’m no expert, but I’ll play!

I think:
1: No, I think to dismount, you must be able to move, but I don’t think it counts as a move. Sort of like dismounting doesn’t (if I recall) provoke defensive fire.
2: I think using him as a spotter would restrict him from moving.
3: I think that would work. A bit outside the “spirit” of the rules, but I don’t recall anything that would stop you.

I don’t have rules in front of me, but that’s how I see it. Would like to see a more seasoned player’s response.

I'll try this, it is my understanding of the rules, I might be wrong, then again, I might get it right.
1. Mounting & Dismounting occur in Movement Phase. You would be Spotting in the Assault Phase, so it would not. However, you must remain in the Dismount hex & not move in the Assault Phase. Though not considered a move for Defensive Fire, it is considered a move regarding further action for that unit in current phase.
2. co1191 has it correct, Spotting is your only permitted activity in the Assault Phase, as per "Chatting on the Radio" restriction.
3. Not as you describe it. However, you could spot several shots, then move transport, but once a unit ends it's action & another begins, previous unit's part of the turn is complete. You could also move transport & then spot. I do think however that Rangers can actually spot, move and spot again but they cannot at any time spot for aircraft, only artillery units.

What about a spotter on a vehicle with "Fighting Platform". Could the spotter use it's "Chatting on the Radio" to spot without dismounting?
