Light gunner or observation?

[Topaz09]

Instead of going cavalry, I'm going to the gunfuckers, min issue is which role, I've got my eyes set on light gunner or observer. Could I have some advice on this and also could I change if I wanted to?

could I change if I wanted to?

Of course you can, it's all the rage in these enlightened times. The Army will even give you time off for the op.

Good luck.
