hidden units and transports

[Hugmenot]

No, transport units are units and count towards the number of hidden units.

If your opponent agrees that transport unit should not count towards that limit if hidden with a gun, do so, it will not tilt the balance in any significant (we've done it on occasions). What I generally do is set up the transport units not-hidden where they can get to their gun in a turn or two, which still covers a wide area for my opponent to not be sure of their location.

You will see something similar to what you suggested in your last paragraph in a future game. And thanks for the feedback because it confirms what we suspected.
