The Competition & Teaser Thread

[ComradeP]

What you mentioned. The point I was trying to make is that PzC Moscow '42 has 50 metre elevation differentials. The highest obstacle in a hex in 10 metres high. To be honest I'm not certain on the actual mechanics, but assuming a height determination is done at the centre of a hex then its easy to see a 100 metre hex from a 50 metre hex that has an intervening hex that is 60 metres high (50 metre base +10 metres for obstacles).

True, but in terms of abstraction it can lead to odd situations. For example: a unit in the center of a 100m high hex might not be able to spot a unit in the center of a 50m high hex if it's on a plateau, or the other way around, because the unit on higher elevation might be 125 meters from the start of the slope down. The unit that's higher could only spot the unit at a lower elevation with certainty if it were at the beginning of the slope down. In the case of a reverse slope defence, there might be an enemy unit on that slope down that the unit on top of the hill isn't aware of.

If the unit is on a regular hill with a fairly narrow peak area, both units might be able to spot eachother, but it's different for a plateau.

When height differences apply, line of sight also becomes a cone rather than a line of sorts, so any vertical obstacle in its path either in the hex the unit is in or in the next hex could block line of sight to part of the other hex.

Anyway, this is all abstract and it usually isn't a problem. There are uncommon situations where I initially expected a unit to be hidden when a unit in a certain hex tried to spot it but which wasn't the case when checking the visible hexes for that hex.

Units will not ignore AOF unless they have definitively been spotted or have fired themselves and removed their concealed status.

Thanks for the answers so far, but I'm still wondering how a unit would detect it has been spotted, if that's no longer automatic.

Using your example: let's say the enemy recon unit used recon spotting and suddenly the units he's adjacent to would be revealed. However, based on what you wrote earlier, the hidden units wouldn't be aware of that because they don't automatically detect they've been spotted.

What would trigger the defending units to open fire?

Also: let's say there's another attacking unit within normal visual range (as in: it can see the hex where the previously hidden units are in), would the defending units just be revealed to the recon unit or to this unit as well?

If so, and if the defending units don't detect they've been spotted, you could have a situation where the attacker can call in artillery fire possibly followed by direct fire where the attacker fires first, simply because the defending units are not aware they've been detected and are sticking to their opportunity fire preferences.

So, to break what I'm describing down into individual actions:

1) There's a (stack of) Soviet hidden unit(s) in a hex.

2) A German recon unit of a target type the defending units won't fire at moves adjacent to the stack.

3) It uses recon spotting to spot the hidden units. Possibly, air recon is used instead of recon spotting, but the result is that the Soviet unit(s) is/are revealed.
-First question: what happens to the opportunity fire preference of the Soviet unit(s), assuming they don't detect they've been spotted like you posted earlier?

4) Another German attacking unit is within visual range, but outside the opportunity fire preference range of the Soviet unit(s).
-Second question: are the hidden units now also visible to this unit?

5)In case the answer to that question is "yes", the German player now calls in artillery fire.
-Third question: what happens to the Soviet opportunity fire preferences now?

6) In case the answer to question 2 was yes, the German player selects the second unit (the one in visual range, but outside opportunity fire preference range) and fires with direct fire at the defending Soviet unit(s).
-Fourth question: what happens to the Soviet opportunity fire preferences now?
