The ranger blazes the trail.
Literal
Ranger [subject-が] path [object-を] opens.
拓く (ひらく) means 'to open up, to blaze (a trail), to pioneer' — a more dramatic and literary verb than 開く for the same reading. レンジャー evokes military or park-ranger contexts. The brevity gives it a motto-like or narrative flavor. The sentence could describe a literal trailblazer or be metaphorical for a pioneer.
