It's true that many move sequences can be collapsed to a single maneuver. However, the area control remark is inaccurate: controlling or occupying the 3 alleys is very important and requires careful positional play. Getting the right "lane parity" to attack pieces frontally is crucial here, as is pincer movements around the lake with multiple power pieces. You seem to view Stratego as a superficial and repetitive game, but high level play goes considerable beyond a few bluffs and mechanical exchanges.
