The musketeer feels like he's a very much tamed down version of the three musketeers rather than an actual musketeer. The French Guard was an odd duck in being named after musketeers. These were elite soldiers who should have boosted physical stats and decent skills. They were also skilled in horseback combat: you should be comparing them to knights and samurai in terms of skill level, and perhaps better, as they were picked troops, rather than generic.

A proper musketeer (the ones that actually fought in all the wars) would have his musket, the soldier skill, and a very poorly trained in hand to hand weapon like a short spear or a sword. Actually, he's as likely to have points in fast draw for loading his weapon as he is to know how to actually aim it.

Along side musketeers would be pikemen (a classic unit), creating the classic "pike and shot".

Another classic at TL4 is the "Man at Arms": a foot soldier clad in full plate and armed with a polearm of some sort. Nastily effective if no one is using guns on a large scale.
