UIName

Generally the first flag on an object, The content of it is interpreted as being the name of a string in ra2(md).csf. That string should contain the name of the object the flag belongs to.

Example

[E1]
UIName=Name:E1

Meaning: If the game is in any situation asked to output the name of the unit "E1", it will respond with whatever is put in Name:E1 in ra2(md).csf - "GI", in this case.

Seems to have no effect when used in the [ General ] section of the rules.
