Take take a reasonable-sized force (I always use about batallion-strength) and attack the bridge, then take your recce squadron and your 9th Airborne Field Company RE, they both got jeeps so they are fast, let them both attack with the help of the 'secure bridge' option. When the attack is in progress usually I get fire-support from my artillery, and 9 out of 10 times i get the bridge intact. (but remember to use 'save game' before the attack

)
