Yes, You will spot it and what it covers if you start looking for it.
Some of the older armour systems combine soft armour with plates, so they provide all around protection from pistol rounds with certain points being protected from rifle rounds as well, the soft armour would protect form some shrapnel as well. You will see that kind of armour with the bulkier looking systems with groin protectors and neck guards. But people have moved away from that because it's too bulky and now many just wear a plate carrier. Some carriers and suits have provisions for side plates but they are often taken out by the wearer and so usually it seems they just have a front and back plate.
