There was some discussion on this already, nevertheless, I would like to refresh an interest about this topic. I am not sure if it is compatible with "plain" RTW 1.5 engine (with the BI 1.6 of course it is). I would be grateful for this info: 1) trustful reports of tests with usage of the swimming unit setting in descr_formations_ai.txt script file - swimmed????, 2) reports of CTDs and/or some other markers of incompatiblity with the RTW 1.5 engine.

Shortly speaking, is it useful? is it harmful?

Plese, give me only valid info. It is no worth for me to talk that they should swim, or that modder XX has said that he implemented the swimming and you will not give me some validation to this, something concrete such as : with mod YY the units swimmed indeed and the respective link to such a mod ....
