It sounds like yet another ill-thought-out pseudo-wannabe-political yawn-fest.
Firstly, constructing military barracks to house large numbers of troops on your country's frontier is certainly not going to endear you to the people on the other side of the border. One of two things is going to happen: either the neighbouring country will follow suit and construct similar fortifications and proceed to man those fortifications with large numbers of troops, or the neighbouring country will decide that it might be better to counter the threat by drawing up plans to halt the advance of any enemy troops that might cross the border by building defensive works farther behind its own lines.
If the first situation were to come to pass, it wouldn't make for a very desirable place to live for ordinary citizens as most people wouldn't want to live in a place where war might break out at any moment.
And if the second scenario were the one to come to pass, it would essentially be an outpost in the middle of nowhere that served no function in whatsoever unless that territory decided to mobilise those troops against its neighbour one day.
As with any volatile border situation, the first kingdom would expect and demand that the neighbouring kingdom take steps to insure that nothing and no one crossed from one territory into the next without permission. Allowing masked vigilantes to exact their own brand of frontier justice certainly doesn't instill a sense of loyalty and obedience in one's own soldiers.
And if such a group were to attempt to take control over an area where a large number of government troops were garrisoned, that group would likely be wiped out by men who served under any leader competent enough to recognise the threat.
Is it "original"?
No, it's imbecilic in every conceivable form and fashion.
