The key to better communication is to have more information to work with as a whole.
Alien queens have it quite easy compared to COs, because they have a very easy to use "overwatch" system that even has a zoom feature, allowing her to see what her xeno's CAN'T see, allowing her to warm them of possible flanks and other threats. She can see all and then some, and thus it makes leading her hive a lot easier. It also helps that there isn't as much text spam as a CO with 4 comms active at once, so she can read and give orders more easily.
Human COs don't have it as simple. They have a tactical map which gives them very basic positioning information, 4 overwatch computers that he has to wrangle from the SO just so he can see what a marine in a particular squad is doing or what a small part of the field looks like in detail, has to deal with a clusterfuck of marines screaming conflicting information in his ears to the point that sometimes he can barely make out what is going on due to how fast the text scrolls, and just the general fact that he has to juggle so much to get the smallest thing done makes for a very stressful.
I know the CO isn't supposed to do everything, but sometimes I wish he had a special "super overwatch" computer of his own so he can easily jump from one marine to the next, has a sort of zoom feature of its own so he can see more, a more detailed tactical map, and whatever other stats he can track to keep things nice and orderly.
