Yes i get it ! But even so the GTVA should of been able to swarm the NTF ! Also that does not explain how the GTVA managed to loose control of several nodes in favor of the NTF.
GTVA Command is composed oh lobotomised retards who make theyr strategical ecisions based on good hand at poker.
Or they got drunk most of the time on Bosch Beer and made all they decisions half past out. 
yes the GTVA is formed of retards but dont forget even a retard has a brain. the GTVA like today in the usa and a few other countries, you got the governement bickkering about what to do about veitnam, lets put it like this for the moment, veitnam is the NTF and the GTVA is well usa, canada, australia, uk.
now you got a great stratiest who is bosch who is the gruilla leader in the veitcong, hes the most powerful on the enemy side then got the GTVA leaders who put it this way are bickkering amoung themselves to decide what to do, this just puts the GTVA at a serious disadvantage already because there is no stability from higher up, meanwhile on the enemy is concerntrated and waiting with several plans and several more continency plans, just incase things start sliding backward, now without the main weapon from the GTVA the collosus meaning the b42 bombers, the gtva cant really do much in term of anything except fight. several months down the line and bosch has several key positions in the war wrapped and several cities keyyed in then, he then gets pushed back, then they push the the GTVA back with plan b, and key the cities back this time plan b is working, the GTVA is getting cut to pieces quickly and without the Collosus (b42 bombers) this war is heading to the NTF (veitcong).
and in the same war with the b42 bombers, all the GTVA needed to do is to chop off there hands. send some covert ops in and bomb the key recruiting grounds, weapons factories, and sniper the key leaders before the veitcong could of responded, then send the main guns of the GTVA in and destroy the rest, NTF easily dealt with.
that atleast how i see the battle against the NTF
