You will have to wrap your head around the way filemaker works. It's indeed a slightly different way of thinking.
If you want you can look at some screencasts on my youtube channel.

They might give you a good idea.
I don't know anything about your database. But I'm thinking you need a view that shows you all techniques and a script that performs a find to show only certain techniques. For instance only weapons techniques.
This script can be triggered by a button.
You could also put several buttons in your header to show you other techniques.Each button will perform a find and show you a different found set of records.
