Trivial 2 - Because Secure Territory operation names include the enemy force being acted against, the mid-mission Mission header always reads : "MISSION: Secure Territory: (Enemy A) vs (Enemy A)". Which makes it look like they're fighting themselves. "Meat heads vs meat heads" in the pictured example.
I enjoy the mental picture of a street full of Rob Reiners throwing down with each other, but I don't think that was the intent.
Trivial 3 - Same pic. "Bare hands" replaces melee weapons when outside of melee range, but doesn't get replaced when the player gets to melee range (until after an attack with their weapon? I usually win the fight in one blow, but I think that's what happens). So there's one "swing" of combat where they read as being unarmed but actively attacking with their melee weapon of choice.
