4th edition hidden rules and artillery recon

[Hugmenot]

sure: a hidden unit loses its special status and must be placed on the board if......an enemy unit...conducts any type of fire.

In my opinion, the "...conducts any type of fire..." refers to the hidden unit. My comments in brackets.

"A hidden unit loses its special status and must be placed on the board if an enemy unit is able to spot it, or if it [the hidden unit] moves or [the hidden unit] conducts any type of fire.
