OK it meets the criteria of squadron strength since only 3 made it to any operational squadron.
I can't find anything about combat though so whats the source on that & what did they do.
I cant really find a 100% answer to the combat question. Some sites say it took part in various combat rescue missions and long range reconescence(Yea, spelling sucks, shame on me). Others say it never saw did this.
They do all agree tho it took part in an attempted rescue of people trapped from snow, But crashed due to poor weather.
Many Draches were bombed tho. So if you count being bombed as being part of "combat" then thats its official combat history

The varients were:
Fa 223A - for anti-submarine warfare, to carry 2 x 250 kg (550 lb) bombs or depth charges.
Fa 223B - for reconnaissance missions; fitted with a jettisonable fuel tank.
Fa 223C - for search and rescue duties, fitted with a steel winch cable.
Fa 223D - freight variant, for resupplying mountain troops.
Fa 223E - dual-control trainer.
But from watching various videos on it, I believe only the C,and D models were ever produced and maybe 1 A model.
Cool video on it:
