This markup is old and being carried over from the Unit page. Should it really be taking its lead from more modern pages where the basic content structure looks like the following?

```html
<div class="wrapper-content wrapper">
  <section class="content">
    <article class="content-primary" role="main">
      
    </article>

    <aside class="content-supplementary" role="complimentary">
      
    </aside>
  </section>
</div>
```
