Possible ground combat bug??

[Q]

I experimented a little bit in the combat simulator with ground combat and troop designs (SE Version 1.49) and found some strange things:

1.) Shields seem not to work. If you make troops with identical weapons but one with 240 shield points and the other with 100 armor points, the armor troops will clearly win if in equal number.

2.) Weapons range seems without effect. It seems not to matter if you use the small incinerator beam with a range of 1 or a weapon with higher range with the same damage.

Because this is completely new for me, I would appreciate any confirmation or contrary observations before I mail it to MM.
