"CV Select and CV War Room:

1. For a CV to participate in a CV select/ war room, the CV must have bombers
and bomber pilots loaded regardless of the armament carried by the CV.
2. For a CV to participate in a CV select/ War room, any CV3 or above MUST
have both fighters and bombers loaded. CV2 and below are permitted with bombers only, but are recommended to have fighters as well."

Nothing wrong with using guns. You just cannot FW or be a high level BW.

if you click the rules tab in game it will bring up the rules for you.

ok cause i had players in a cv room complaining that I had guns and that it is against rules to use guns in cv room.

I was even banned from a cv room cause I had guns...

And yes I have FP and DB loaded :)

And yes I have screens of this

cv 1,2 can do what ever you want,
cv3 or above must have both fighters and bombers, you can even put just 1 bomber plane, but you have to show a "B" or "T" in the waiting room.
no limitation for gun or HH.

Guns are allowed in ALL CV Select rooms (and are actually encouraged by a majority of the players).

Mainly the only players that try to say they are against the rules are players that are trying to AB the credit gain (looking at past experiences and common knowledge).

If you have screenshots of being banned from a CV Select room simply for having guns, report the host for it and include those screenshots as evidence. The less ABers on the server, the better!
