Good job. You need to be fit, bright and have the ability to multi-task. You need to understand and be able to work with the Inf and Cav. Unless you have sigs quals, you'll have to start again (I would think as I don't know your rank, trade etc) and work your way through the OP path.
If you have an int background, then there are areas at a higher rank to work in an HQ and do Arty Int.
