Honestly, this seems weird.
Sure, we often see the lower ranks swarming in mass wave 'victory or death' attacks. And most of nods bottom tier and second tier stuff is intended to be cheap and replaceable. (buggies, bikes, scorpion tanks) But when not conducting global offensives they often use guerilla tactics. Stealth is one of their major tactical and strategic tools after all. That, and in the case of militants they often blend into/are recruited from civilian populations...
I've said it before and I'll say it here again now. Nod doesn't feel like Nod currently. They don't feel like smart, cunning enemies, and they don't feel like the de-facto government for huge chunks of the planet. They feel like orcs. Attacking out of blind hatred and a need for 'Waagh!' But with little overarching strategy or objective.
I think you are grossly underestimating the proportion of their strength that they're committing to these attacks.
These guys
do have a lot of resources. They have a tiberium economy, like we do, or rather, one that runs more efficiently than ours because Nod knows more about tiberium than we do and is willing to use unsafe methods we reject. But unlike us, they aren't pressured into spending vast amounts of resources on arcologies for the masses or giant space stations or whatever. Now sure, they have less actual industry than we do- but they also are in a better position to concentrate what they have on building up a war machine.
I'm sure Stahl doesn't like it when he loses a Redeemer. But we deploy MARVs by the
dozens; I'm pretty sure Stahl has at least a double digit number of Redeemers and can replace a lost one within months- broadly the same time scale it'll take us to patch up the armored division Stahl tore up during his counterattack against our forces.
...
Also, one point I feel like your longpost misses is that these guys
are committed to the capacity and intention to wage war with GDI. As such, it is necessary for them to at least occasionally test their forces in battle against GDI. If nothing else, they need the opportunity to learn from failure by devising better weapon systems to counter whatever was defeating them before. Notice that probably
unlike Krukov, Stahl managed to recover much of his force, and we don't know what total fraction of his forces he actually used...
So for them to expend forces they could conceivably hoard makes sense, because otherwise they don't know how their forces will perform against us. We're constantly deploying new weapons and increasing the availability of old ones, so if any of the warlords go more than a few years without a big push against us, they're likely to be caught by surprise facing our capabilities.
Stahl and Gideon are the prime examples, but also Krukov is partly guilty of this. They're launching major attacks against GDI population centres/strategic locations in the case of our marv hubs. But, those attacks failing, leaves them weakened and makes them look bad. Sure there's the politicking of *attacked GDI Damaged X* But it's rarely meaningfully increasing the warlords own power, indeed, especially in the case of Stahl and Gideon the opposite seems to be happening as they lose soldiers and expensive gear to mixed results at best. In some cases the higher warlords are removing ambitious underlings by sending them at GDI, but this kind of implies that at least in some cases they're hedging their bets against the likelihood of the forces in question being destroyed or heavily weakened.
I think it likely that for Stahl, the forces actually expended were a small enough fraction of his forces that sacrificing them for tactical data and an opportunity to (if successful) materially weaken GDI positions in southern South America could be worth it. Again, these guys
can replenish their forces, and when given years to rebuild between campaigns, it's safe to assume that they have done so.
Your allegation that Stahl is "constantly" attacking is just nonsense; Stahl himself hasn't pushed a single major offensive against us until this one. Remember, we've been told it's likely that his subordinates insisted on the attack on the MARV hub. Even then, that's only two attacks in several years. For a guy who controls much of the resources of a continent, two corps-level offensives in multiple years of low-level warfare is
nothing.
About the only warlord who's really overextended themselves and has probably taken more losses than they can easily afford is Giddyboy, and he's noted as being the least competent of them all as a strategist.
...
And as for your alternative suggestion for Stahl, of attacking GDI harvesters and patrols more intensively? That if anything makes things
worse for him against tiberium because it means GDI isn't doing as much to hoover up tiberium in the Yellow Zone or hold back the encroaching Red Zone. And it doesn't leave him prepared to know what to expect if Kane shows up and orders a pitched battle, which past Nod experience strongly suggests he'll do some time in the next ten years or so.
Just keep smashing your skull against the brick wall Stahl and maybe he'll break through? With Bintangs success I'd expect him to spec into an airforce/navy in order to disrupt GDI shipping/trade to and from the south american blue zone. They export loads of processed tib/raw materials and import stuff they need. If he built up a local navy he could perhaps quickly gain local superiority and if he was able to cut or disrupt shipping in the atlantic region between west africa and South america he could possibly hurt GDI badly. Bombers, subs, small missile boats, larger battleships etc. Whatever. Point being, Nod/Bintang Navy recently chased GDI out of their region in a big way. I'd expect Stahl and others to focus on negating GDI's advantage in logistics. The fact Stahl is ignoring that in favour of armoured warfare...
Who says so?
For all you know, the submarines that launched the Manchester attack were Stahl's. It's not like they carried around ID and told us who was operating them, and the submarine attack would be just as consistent with Stahl's methods (launch a low-profile attack with cruise missiles against enemy industrial complexes) as Bintang's (use bote). And it's a lot closer to Stahl's backyard, much easier for a submarine to get to without overstraining its operational range.
Honestly, I feel like you're starting from some very narrow assumptions about what Nod 'should' do and also what they 'do' do, and why they should and do
do it... and then assuming they're stupid because of contradictions that exist mainly in your imagination.
Even Stahl lost a Redeemer, we can probably build entire Predator battalions in the time it takes a warlord to replace something as high end a redeemer.
Yeah, but on the other hand, Stahl
took out entire Predator battalions with that Redeemer; the 13th Division was pretty well chewed up. By the time it's ready to fight again, I bet Stahl has a new Redeemer.
