. . .Cultural exchange in sauna:

But the coalition-building has also led to some odd cultural exchanges. Chief among them has been getting foreign officers used to the Swedish habit of socializing with little or no clothing in the warship’s sauna. During off-duty hours, the sauna is at the heart of socializing on the ship. Spanish, German and Norwegian officers meet their Swedish colleagues there after long days in the Indian Ocean searching for pirates, responding to their attacks and planning escorts for ships.
