I have a mission, The_Slot_42RedArmor00.mis seems properly built, but I always get "Wrong Target" any ideas?

Do you have RedNone mission for that map, if you don't have that mission other missions for that map don't work on some PC.

If that's not the case check spelling in mission name and in conf.ini entry. If you have working mission for that map rename it into Armor mission and than try to load mission, if mission loads than error is in Armor mission.

Does there need to be an "armor" unit there? Can it be stationary?

I have some MG42s, and I even hid some trucks in the trees in the hopes the target mattered. Actually, my last version has a tank hidden as well, no joy.

On a similar note, I have yet to use "Bridge" do they require a bridge, or can I use it for something else?

You don't need armor in Armor mission, you don't need to set targets too, these mission names serves only for QMB engine to pick desired mission. You can easily make QMB where you can use numbers instead Target names but as QMB doesn't have briefing it's good to have target names to give players info what is his task in mission.

Only requirement in QMB templates are 4 flight per side and it's good to have player in first flight.

I took one of my test mission and gave it the same name as you, added new entry in conf.ini and mission loaded without problems so it looks to me that it's not general problem with QMB.
