What do the red circles with the numbers mean?

When you hover the mouse over the hex, look in the "message box" and it will tell you how many supply were lost due to interdiction. There are also circles for powerpoints and resources lost due to interdiction.

Thanks, what's interdiction?

Interdiction is what air and ships do to things that are sent to your units from either other units, or production locations (Cities for instance). Since all units need supplies to function optimally, they are sent some. In a sense imagine planes (or subs, or other ships) sinking/detaining/preventing/disrupting delivery of the transport network.

Understood. How do you stop it.

Depends on if you mean stop the red dots from ever appearing (you can't) or how to prevent interdiction losses. The best way is to get fighters in the area and set them to intercept. At sea, find a ship type, say destroyers, that have anti-supply interdiction, and put them where they can intercept attackers. You need to set them to intercept. You can check the ratings by clicking on the SFType and looking through the ratings. These interception units have a radius that you can also find in the ratings, I think 50% of their movement radius. Basically, you need to get enough interception points up to negate the anti-supply points, which in your case is probably caused by dive bombers.

Thanks for the clear reply. Im inflicting supply losses now (blue circles) & reduced my losses, I didn't have my fighters set to intercept. I read somewhere on the forum that the fighters will use fuel when they are on intercept, is this true?

While intercepting anti-supply fighters use fuel for action of being up on patrol trying to intercept dive bombers, etc that are conducting anti-supply attacks. They get charged for 50% AP once during the turn. The same is true for aircraft conducting anti-supply (interdiction) missions. They get charged 50% AP (or something like that there could be something extra for attacks as well). But, yes there is a fuel charge. And no, it can't be exploited as it is caused by your action of sending planes up to patrol the skies.

I think what Ormand is referring to regarding the exploit, is that if Fighters set on intercept, were intercepting bombers, that flew missions, instead of intercepting interdiction, used fuel, that could lead to an exploit. You could send up 1 fighter at a time, and drain all the intercepting planes for 1 combat round of fuel (10 APs of fuel). Thus normal interception takes no fuel.

If all my fighters were set to intercept & the AI never flew any air missions during a turn will I still use fuel?

Yes. If they are able to get up, that is, they pass the readiness check, etc., they contribute to intercepting anti-supply, then they spend fuel. The fuel cost for a subformation in a unit set to intercept is FuelForAttack*NumCombatRounds*Qty, where FuelForAttack is what the subformation spends per round of combat, which in PhoenixGame for Fighter I is 10. NumCombatRounds is specified by RuleVar(943) = 5 (max is 10), and Qty is the number of subformations of that type in the unit.

The way the system was set up, it would be rather difficult to spend fuel proportionally on the amount that is actually intrcepted. It would take some work to do. In principle, I could set it up to spend no fuel if there are no enemyunits performing anti-supply attacks. But it is a mission set fo the units, and they do have to fly to patrol the area.

I think that I have to take that back. The amount of fuel expended does depend on the amount of anti-supply being applied. So, I think if the enemy doesn't conduct anti-supply, you don't expend fuel. It turns out that I did indeed put in a fairly complex check on fuel. Actually, it looks like anti-supply must be conducted within the range of the interceptors to expend fuel. It has been a while since I looked at this and it is a bit complicated as it is also possible for allies to intercept during your turn as well.

The effect of interception on anti-supply looks to be for each hex

Total_AntiSupply*(1-Min(Total_Interception/Total_AntiSupply))

Total_AntiSupply is the sum antisupply ratings from each unit on a hex within its range, while Total_Interception is the same for intercepting anti-supply. It is slightly more complicated as it is modified by regimes participating, as in regimes at war with you and regimes allied with you and intercepting with you. And note that it is possible that some of your allies might not be at war with some of your enemies. And note that losses are attributed to each of the regimes.

But, at this time, interception of anti-supply attacks doesn't result in losses to the anti-supply attackers.

Thanks for your help
