Radiation, nuclear warning and bridges?

[Glenn Saunders]

When do you know when the enemy is using nuclear weapons?

For one thing - when a nuke strike happens a disctinctsound plays I am pretty sure.

I was playing as WP in AFNorth in Danube Front 85' (solitaire) and sometimes I see "Radiation" marked on a hex. I haven't used nukes before in the game, so it would seem to be the AI who using them.

If it was a Stock scn - NATO can't us Nuke Weapons until the WP uses WMD first. If your playing a scn you downloaded then anything goes.

1. How do you know when it is possible to use nuclear weapons?

It's defined in the PDT

Which types of units is capable of firing tactical nukes? WP mostly?

Right click on the unit Window and it will say IF/WMD

See the Scn #03 WMD Demonstration

Another question, what is the difference between ordinary bridges and pontoon bridges? do they have different advantages/disadvantages?

Have look at the documentation and if something isn't clear post again and refer to a game, Scn and a hex IDs (bridges) your refering to and I am sure someone will help you out. But generally a bridge is a bridge - you get over a minor river fast than fording and you need a brdige to get over a river.
