You can capture a field the same way offline as you do online. Simply destroy all enemy gun emplacements, and then get 10 of your troops into the map room. You can do this with an M3 troop carrier or a C-47 gooney bird.
The only planes available offline are the drones circling the fields.
You can also play in H2H games for free if you like, and if you create an account, there is a 2 week free trial that you can use to play in the main arena for free. The training arena will also be available during this time, and you can hook up with myself or any of the other trainers for some instruction if you like.
