Failed Observation

When given an Open Fire order and the observation roll is failed, is it allowed to attempt another spot and  to re roll for a different target in the same action, or is the action lost?

Alternatively, could it re roll for the same or a different target on the second shot of the order?

Nope, no re-rolls. You get two actions so two chances to spot, but you announce both before rolling any dice at all.

Thanks for the reply.
Therefore, a failed spot means the order is over.

No, one failed spotting roll does not end the unit's activation. You still get your second shot!

that makes perfect sense:D

can I ask if there is a rationale available anywhere detailing the approach, please?

My fellow players are interested in , positive way, as they are new to the game and haven't been able to tell them.

You get two chances to shoot in an Open Fire order. If you are doing direct fire then you must spot first. If you fail on your first action then you try again on your second one. I'm not sure there's any more rationale than that, but if there is you'd have to ask Warwick.

thanks Nazrat for your replies
