1) Use bazzoka or other AT teams against cannons. I was playing a rather long time before I realized that they destroy cannons in one clean shot. So do what you can to get the cannon revealed, sneak up an AT team and one shot later your tank path is clear.
2) Don't discount mortar's on tanks. Of course they work decent on open topped tanks. They're also not bad against light tanks or the old french tanks. The heavy mortars (Chemical or 120 mm) can also damage Stuart or Sherman's. It can take a lot of shells to get an effect and sometimes you don't do more than damage them, but a damaged or immobalized tank is nearly as good as useless in many situations.
3) Put snipers on defend rather than ambush. They're smart enough to stay hidden and will fire at longer range targets. I thought snipers were useless until I read this tip somewhere.
4) Flame and Assault team positions. Use the F7 view to see which exact guys is carrying the flame thrower. Make sure he is within 30 m of the target position. You can move a squad into a building or hedge, move them off and move them back on and the flamethrower guy might be in a different spot even if the team deploys the exact same way. Use this to make sure the flamethrower's LOS isn't blocked by teammates or further away than rest of squad. Nothing is more frustrating than a failed flame attempt that could have completely saved your guys.
One follow-up on the virtual PC option. It allows you to allocate how much memory you want for the virtual operating system. I think this has helped me with the scroll speed problem that others have mentioned when running CC5 on newer/faster machines. When I run the game in Vista (non-networking) it scrolls too fast. Run on XP in virtual PC and the slow scroll speed is manageable.
I too was trying to get CC5 working with networks on Vista. I had tried most of the solutions listed on this forum but to no avail. For those who are willing to try more drastic options, I have two suggestion.
Option 1: Partition hard drive and install another boot version of XP or something older
Options 2: Same effect but much easier technically. Download a copy of Virtual PC from Microsoft. It's a free software that can be used to run other operating systems in a virtual way within a window on Vista. No reboots and seems robust so far. It's fairly easy to figure out from the free technical help. One catch is that you need an installation disk of some older version of Windows. Buying one might be too expensive, but if you have a older XP, Win 2000, Win 98, Win 95 version lying around from a previous computer purchase you can use Virtual PC to install and run the software without messing with your Vista boot system. Launch and networking seem to work fine.
In August of 2004, Zappi, Homba, Bambam887, RedScorpion and MOOXE all pitched
