Yes, "Commanded Muskets". I've always wondered how much use these were because as soon as the Horse moved, they'd surely be left behind.
I believe Firelock Guard were first used in the artillery park as they were a safer bet,amidst all the barrels of powder, than matchlocks.
Later as the period progressed, pikes grew fewer as firelocks became more common. Even though they were much more expensive to produce.
Therefore, as my tenuous grasp of logic directs, firelocks had advantages: faster to load? More accurate? Longer range? Easier to carry?
Evidently, none of the above.
I'm in a quandry*.
