Hello Joe,
Thanks for writing in!
I see that you have Pro Theme license. To create similar looking website I would suggest you to use header and footer builder. I suggest you to take a look at the Integrity Stack.
In the website I see sticky navigation bar. Sticky navigation bar can be activated by inspecting the Bar > Setup > Sticky bar and select On.
I also see slider element on the website. For soldier I suggest you to use Revolution Slider that can be installed from Pro > Validation > Revolution Slider. Revolution Slider also has the option to import demo slider from Revolution Slider website. Please take a look at following resources to get started. Rest of the page layout can be designed using Content and footer builder.
