Damn Stubborn Titans, Don't do what they're told Options

[Huey The Infecte...]

Tiberian Sun: Firestorm

I am on the GDI Mission "In a box", and have got to the bit where you have to attack the bridge from below with the titans after the tiberium patch with the cyborg commando to the far North East.

One problem - I cannot attack the bridge. Whenever I move the cursor over it after selecting the titans and clicking EVERYWHERE on the bridge, the cursor just stays green and all they try to do is move on to it.

I know this may seem like a stupid question, but how do I destroy it?

Any help would be appreciated.
