Yes, the commander can see the resource nozzles. They are just small because the commander camera is up high so the commander doesn't get lost when trying to find their grunts. If you press Q then S, iirc there is an arrow pointing to the closest node. The hard one to find is the power nodes.

There are 4 powernodes in the map and they are actually not touching the ground (so aliens have a hard time getting to it) but as a result the commander has a hard time finding them. Best way to find them is to highli8ght a big box, ctrl + #number and double tap that #number

This seems really funny... can a commander even see the map? Are there resource nozzles?
