Or just the general stragety when it came to the Mojave Campaign. It was obvious that House was in firm control of New vegas with his army of robots and backing by the tribes. That said why did they fell it necessary to post their largest numbers of troops just south of the city? I understand you want to boost your military presence in the region but with a army of neo roman thugs forming across the river you have more pressing needs. Besides the very fact that they tried to use a foreign military presence to gain support in NV is misguided at best. When you move south of Vegas and can't even build support in the slums, can't kill the fiends, can't provide jobs and housing and such for the slums and city you just present a bad image. You seem imcompent to the populus and worse yet they were.
Speaking of imcompentce the NCR could of been in a much better state of affairs if they would of simply,
"Secured I-15 for trade and commerce into New Vegas (and they would of eventually killed off what remained of the BOS with their larger numbers)
"Move rangers into the heart of rural populations (goodsprings, primm, even nelson) and build relations using civilian not military departments."
"Weaken Legion morale through the usage of non conventional warfare, I mean come on Cottonwood was a prime target for simple sniper attacks."
"Take the offense! Simple attacks on Legion camps in Nevada would halt all further offense."
If most military officers in the game can tell that the wait and see policy isn't working it's time for new top leadership. The problem isn't that the NCR is too bureaucratic but rather the top administators and executives have the wrong stragety for winning and that the bureaucracy needs to be revamped some. Remember without bureaucratic institutions all the decisions would be left to rogue arbitariness.
Here's my compreshive plan
A. Remove all troops from Camp Mccarran
-It's obvious to everyone who's played F:NV that even with Mccarran the NCR hasn't taken down the Fiends, secured Westside, Northside or Freeside and hasn't even made those places better economically. All mccarran does is send a bad message to the New Vegas community that the NCR is ineffective and doesn't care about their interest. The only troops in Vegas would be the MP on the strip. Some people have noted that the NCR is what keeps the Fiends from taking over but I feel like that's exaggerated. Sure they took on a group of rangers but I can't see the Fiends becoming strong enough to kill off Westside. Since the NCR is bad at stopping them anyway I doubt a lack of NCR presence would make a difference.
B. Relocate Mccarran troops to secure I-15 and NCRCF
-This would be one of the easiest things and best things the NCR could do. The prison break was simply a result of an understaffed prison, but with more troops from Mccarran the Powder Gangers wouldn't get free and even if they did the massive NCR presence would stop the rebellion fast. Even the small divison outside of Primm could in the game so all the troops from Mccarran would mean it would be easier. Besides that with I-15 secure the deathclaws wouldn't move in and they could deal with Tabieth and use the radio equipment for NCR propaganda.
I-15 is the most important highway for trade and commerce, and if it was safe, the communities of Primm, Goodsprings and a lesser extent, Nipton would gain more in trade and delevop more positive relations with the NCR. I'm not sure why the NCR doesn't simply appoint a sherieff in Primm or just dispatch one troop to the town for protection. I don't understand why they need a whole division posted outside and why they must put it under matrial law. Hell Primm is probably the most profitable tourist trap in the Mojave outside of New Vegas and it's not even under threat from a Legion or House take over! You all now the Quarry is needed for further fortifcation of Forward Operating Bases and like I said no Powder Gangers=No deathclaws. Plus with Powder Gangers still making the railroad once that's done they'd have an even better position for fast deployments in the region.
-With a full Bat. along I-15 the brotherhood would be in a squizze. There is no way they could take on that many troops and more and more they'd be under threat of being found out. That said I see only a dipolamatic solution or the BOS Mojave falls. I'm about to get off of I-15 but before I do now that I think of it why not just use the two rangers at the Mojave Outpost to secure Primm and Goodsprings?
Goodsprings would receive a one simply to deal with the Cazadors problem and to make sure the Great Khans don't try to move south (though the Cazadors probably solve that). But like I said they don't even need MANY troops. In Primm a robot was able to secure the town. With I-15 secure trade, people, and goods could move into Vegas and Primm and while the Fiends would be a problem the further away you got from the Quarry you could simply take the eastern route by way of I-215 to Highway 93 and go though Freeside.
C. Clear out the Mojave Outpost and secure Nipton highway to searchlight
The road to and from Niption was full of Jackals, mutants and the town was raided by the Legion. Niption itself was a bad place but for supply line reasons and the railroad bridge the NCR needs to keep that highway safe. Remember the canyon with the traps? That shouldn't of happened. The troops at the Mojave Outpost should be relocated to the aboaned farm to reinforce the front line from the Legion (especially with Searchlight gone) and make sure caravans can get to Highway 95 easily.
D. Attack Cottonwood.
-You know the Legion slave camps in Nevada? Or the Ranger station they took on? That wouldn't of happened without Cottonwood. As a matter of fact if Cottonwood didn't exist I doubt they could hold Nelson or that mine. In short without Cottonwood the Legion would have a highly weakened offensive. There would be NO way they could take Nipton under those circumstances. They already had Rangers that could have good sniping positions on Cottonwood and I'm sure that First Recon plus the remnants of the Searchlight would be able take it. It's not as if the Legion could get rapid redeployment from Arizona. And I know that Cottonwood had an outlook too, hell just post some rangers there and pick um off. Overtime they'll run out of supplies and it would fall. Without Cottonwood, the legion would be out of Nevada basically.
-Some of you are probably thinking but what about the Legion simply crossing the Colorado at other points? But where? Just talk to the Rangers the Legion can't hardly send scouts into Nevada without them being shot. I doubt they could move a large force and get past the Rangers. With Cottonwood gone the Legion raid Camp would be surrounded. Rangers to the north, Niption NCR to the west, Cottonwood to the east and no way out to the South.
E. Annex Novac
-For simple cannon reasons lets suppose that the Legion would still take Nelson. The large NCR community in Novac would already boost relations with the citizens. I'd remove almost all troops from Hellios One and reposition them at the I-95/Novac overpass. This would be for many reasons, the first would be to secure I-95 for travel. The raiders along the highway wouldn't be able to survive, and to deal with the random creatures along it that would disturb trade routes. Honestly highway 95 is more important than I-15 simply because it's the main way you reinforce the dam, golf, ranger stations, searchlight, Cottonwood etc.
With Novac under control the ghouls wouldn't be much of problem, just have someone spot and make sure they don't venture into the town. As far as Nelson is concerned just send the Novac NCR forces into the town and kill the Legion. But realistically looking at Nelson even with just one Ranger you could take the town. Thinking about it logically the Legion was doomed in Nelson. Forlorn stopped them from advance, the ranger from Novac, and the rest of the Ranger stations from retreat. That in mind just strave them out. Post a ranger and snipe the Legion until they strave. The troops on the cross would probably have to die from mercy killing but that's the safest way to take back the town short of a magical courier storming in guns a blazing.
More importantly and something that I'll touch on later is this, with I-95 secure, Novac generating trade and the Legion back on defense Forlorn Hope could much easily deploy during the second battle at the Hoover Dam.
F. Scavenge Hellios one
Without the Courier Hellios one was basically a giant waste of time, they could only find one skilled worker for the place (no not Fantastic the followers guy) and even if they had more they would still have to destroy all the robots in the place. I don't see why you'd waste the manpower for such an operation. They already have all the power they need from the Hoover Dam and all it is is a target for the BOS, and to a less extent Legion. Would the BOS try to retake it? Not if you take every working part you can from the place and make it unusable. Besides with the whole Bat. Stationed on I-15 the BOS wouldn't be able to.
G. Leave Golf the same
Besides moving a few Rangers from Golf I really wouldn't do much differently about the place, except maybe trying to give some better training to them, besides that Golf is actually a pretty good defensive position for Lake Mead and it keeps the Legion from a direct attack on Vegas itself. Hell if they could just get better training.
H. Allied Technology and other outer Vegas positions
-While I'm for getting rid of Mccarran Interstate 93 is the final link for NCR citizens to get to Vegas and caravans. That said the Highway 93 and Highway 95 intersection is a great place for NCR troops to be stationed though they need to take a more active role in keeping the highway clear of gangs from the intersection to Novac. The random NCR troops along 93 are fine and in general they do need a NCR refugee center. In general the NCR shareropping operation is fine and the need for the water pipeline to remain intact means ALL troops shouldn't be removed from outer vegas because Crimson Caravan supply lines are critical to trade too.
I.Bitter springs and other Northeast positions
All the refugees from Bittersprings should have been relocated to Allied Technology and Highway 93, that way they can be moved deeper into NCR terrority or something, that refugee camp is simply too vulnerable to attack from a raid. The network of ranger camps would need to be reinforced and that's where I would reposition some of the Camp Golf elits too. If there was any place the Legion could still attack it would be from the Northeast section of the map. But you know it could easily be done, without Bittersprings as a point of attack I don't see how a Legion raiding party could take on some first recon shooters or in general a forfeited group of Rangers.
J. Other things that would have to be done for the offense
In game there are what 2 offical locations in Arizona the Legion operates from. The Fort and Legates camp. If you've gotten rid of Cottonwood and gotten the supply lines down the Legion is outnumbered, as no offense, and there sitting ducks for a nice artillery bust. If the only two places the Legion operate from are those two places then in a Battle they'd lose outright. The reinforcements from Forlorn Hope would overwhelm them, and even IF they took the Dam after an artillery blast most of the rank and file are dead. Hell even if they win that battle if you send in the Bat. From I-15, troops from I-93, rangers up and down the river and finish them.
