Do NOT include connected articles on overly detailed or small subtopics. There are probably more than 1,000 articles that are in Category:Vietnam War and its subcategories. This template is focused on the most general overview possible.
The template currently includes no people. This may be the wrong call, but I suspect that once a single person is added, the floodgates for including 30 people will open up. I think the generals/politicians/activists/etc. are adequately linked in the articles as is, so.
