Overall strategy

The final phase of evolution for the musket line of infantry, Rifle Infantry represent the most potent of their kind. They combine the strength of the Grenadier with the range and line of sight of a Marksman and the cost of a Line Infantryman, making for a very potent infantry unit that is extremely tough, and almost able to take out any land unit, bar artillery at a distance.

As such you should then use these units to hold lines of battle, forming a human wall to protect artillery from cavalry, and to support your own cavalry in the field. Just remember to bring your own artillery and you should be fine, even if your opponent were to deploy machine guns or rockets against them.
