Help filling out a DA formn 4187 to volunteer to deploy.? - da 4187

I came from Iraq after a brief introduction, a few weeks ago, and I wanted to go with a unit in the Post in June

Can someone tell me the right way to fill the 4187 to?

In addition, you can deploy the volunteers with a specific company?
