quote ACY3

Once the MCV appears on the map and gets stuck, I start mounting up a force to take out one of the Nod bases. I usually go for the infantry base, but I know some people choose to go for the vehicle base instead.

Build up several APCs filled with Riflemen and rocket guys, and a small group of engineers, then drive the APCs carefully over to the infantry base. You should be able to destroy all their defences fairly easily, then bring in the engineers when the coast is clear. Capture all the structures, and you've got a fully working Nod base, with the ability to build Air towers, refineries and whatever else you like.

Then you can either go for the Tank base, or go rescue your MCV. With such a large and powerful force, there should be little to stop you from moving your MCV back to your base. Split your units so that some are in front and some are behind your MCV, since enemies can appear from both sides.
