UN and mines

[Karagin]

So I was running a test battle, mixed UN force on the defense against the Red Horde (and they did have a horde of armor...wow) all set in 2017 at an exotic location...

So I bought wire, mines, etc...set my troops and bunkers up, put trenches in, wire, some dragon teeth, and then I go to place land mines at spots to further channel the enemy into my nicely placed AT Guns and ATGMs when this message pops up...

CAN NOT PLACE MINES AS AN OTTAWA TREATY SIGNATORY

Wait, what? Oh right the UN did put that treaty in place...so now I had to rethink my whole plan...well more wire and dragon teeth it was. Nice reality check.
