as we noted on recent G2G about the change
The old {{1776}} was a project box and had a single parameter |category=
The new {{1776}} is a sticker and has mostly the same parameters as the other military and war stickers
The sticker code right now attempts to handle to old, single |category= parameter and all the new ones. Once Ales runs a routine to change all of the old |category= to the ne |unit= format, the code handling the old style will be removed.
as to specifics, {{1776|category=4th Virginia Regiment (1776), Continental Army, American Revolution}} should be changed to
{{1776|branch=Virginia Line|units=4th Virginia Regiment (1776)|unit=4th Virginia Regiment (1776), Continental Army}}
if he also served in the 8th & the 12th then it would be {{1776|branch=Virginia Line|units=4th Virginia Regiment (1776); 8th Virginia Regiment (XXX)|12th Virginia Regiment (XXXX)|unit=4th Virginia Regiment (1776), Continental Army}} replacing XXXX with the year of the regiment he served in. since |unit= is only for a single category, to add to the categories for the 8th and 12th, you have to use [[Category:xxx]] for each of them. headers for missing data are shown so that people can see the information needs to be researched/found
as described on the 1776 Project Needs Template Update category page, profiles are added here if template information is missing, and it explains how to bypass the edit check for each field if data research has not found the information, i.e. unknown
the purpose is not to categorize every detail of a persons life, but if you feel it necessary to add a profile with military service, and the civil/patriotic service you can do so using a second {{1776}} sticker noting the non-military service.
Also, a sticker highlights information that is in the biography, not duplicates every word.... so if you want to further describe military/civilian service, do so in the biography section.
