Underwater invasion

[SurvivalistMerc]

I'm about to make some sea king's goblets. Two questions:

1. Is it cumulative? I seem to like having extremely large forces and often find that the more troops I have in a squad, the less often it will rout. I'd like to give two to the same commander for 100 units under his command to go down and teach those silly ry'leh squid-heads who's boss.

2. What happens to archery underwater? Ideally, I would expect it to be useless, but I would also expect the difficulty to be getting the archers down there. Maybe decreased range? Just curious.

Thanks again to all the experienced dom players who help us newbs.
