Where can I learn to write proper counseling statements for my soldiers?

I'm not sure what a "proper" counseling statement is... That said, perhaps the technique you should start with -- What topics do I want to cover in a counseling? Write as you would talk -- Positive, negatives, courses of actions, potential repercussions, professional/personal development, etc. The more you counsel, the better and more focused your writing will become. And of course, there are "counseling technique" books you can find online to jumpstart the brain and inspire your creative juices -- Good Luck!

Start with counsel quick it costs money but there are a lot of examples

Have you look at ncosupport.com tons of examples for almost every incident you could think of.
