The original conception of a strategic bomber was that of an aircraft which was designed to go after targets which would yield strategic effects. For example, the B-1 was designed to penetrate Soviet airspace (integrated air defense threat) and deliver a nuclear payload - a strategic mission if I ever saw one.
So, we can generally associate certain forces with certain effects at every level of war (ends, ways, and means...IF you believe in that voodoo), however, that does not preclude the use of those forces for other missions.
A primarily tactical asset can have a strategic effect. The opposite is true, though common sense says that would be a waste of resources.
