I hope you are right. I build Rohan cavalry themed decks for Helm´s deep and attack on Orthanc and it would be weird for Frodo and Sam and Smeagol to try to secretly creep through Brown lands and Ithillien with a huge Rohan battalion behind them.

And to quote Trialus: "Woohoo!! Rangers and traps!!" indeed.

One of my favourite monents in the books: sad grim captain Faramir resisting for a little while with his small group of rangers against the mallice of Sauron before retreating to Minas Tirrith and undestanding Frodo and his burden letting him go with all help he could spare.
