The collapsable tags should really only be used when there will be a lot of information across multiple sections, so visitors can scroll a much smaller list when they start collapsed or can choose to hide them to remove undesired info and make the surrounding sections easier to read if they start open.

For those individual unit pages, I would say the collapsable tag is only needed for each race's entry (factions) and have them start open for the later reasons above.
