Rules of Game

[Murphz]

Hi all,
I have a question for all the community.

I'm recently playing the tutorial (korean war) in pbem mode, my opponent after 4 turns landed with a recon unit at Namp'o (near Pyongyang), that was uncovered, main bridge blowned up.

My question is: is that an acceptable attack? What's your feeling for that?

Screen attached...just want to hear some ideas from you all. My opinion is that some unrealistic attacks are not allowed to be done, yes the harbor was unprotected but is quite impossible for a recon unit to land in any case.
