A Rhino has about a million uses which we will get into in further depth on that unit review, but suffice it to say that they are extremely good. I run 6+ of them in my Marine lists. The key is understanding that you can move the Rhino twice each turn. Once in the movement phase, once in the shooting phase. You can have the unit inside get out, the Rhino moves along side them, they shoot, then it drives in front of them, blocking LoS from enemy units. You can leap frog like this up the table. That's just the tip of the iceberg, too. You can use the Rhino to block your own LoS to be able to snipe out enemy models, tank shock units off of objectives or into template formation, block charges, etc. They are a great tool and even in death, can still serve. A wrecked Rhino still hides Marines! Check out the General Strategies section of the
Tactics Corner for some How To videos on using these tactics.
