Ukraine Crisis Continuing my analysis of the military situation, which is obviously relevant to make decisions about it.
Again, only Ukrainian commanders can know if they have military objectives that can be feasibly attained.
Diplomacy is then informed by this military situation. If you are losing a war, you have less and less leverage as the war goes on. Hence, if one wants Ukrainians to selfless sacrifice themselves and their country to bleed Russia and create a new cold war, then you need to convince both Ukrainians and the whole world that they are winning, even if you know they are losing.
However, obviously NATO and EU also knows Ukraines chances, so Western media repeating over and over the idea Ukraine is "winning" is ... maybe true, or then maybe a lie to justify pumping more arms into Ukraine.
For, the moment the Western Media says that Ukraine has lost militarily the immediate followup question is that "isn't sending more arms into a lost situation creating more bloodshed for other purpose and also a 'low-blow' to the Russians that will be retaliated against us sooner or later" (if you think the Russians will forget ... you haven't met many Russians). And, indeed, the entire purpose of the rules of war is that fighting is done with honor and integrity and rationally based to protect civilians, to avoid cycles of retaliation. Regardless of who is morally / politically, correct, one side wins and one side loses in a war, and fighting with honour avoids drawing things out longer than it needs to be (sometimes decades) which then create cycles of retaliation and no peaceful building.
Sure, the Taliban eventually "won" ... but are Afghan civilians really better off due to all the cowardly civilian-clothed ambushes and suicide bombings the Taliban needed to win an insurgency?
Which is an exemplary case, for whatever we think of the morality of the US invasion of Afghanistan (who had nothing really to do with 911), imagine the state of Afghanistan today if the Taliban followed the rules of war and accepted defeat and there was no insurgency? Regardless of the initial war and it's reasons, imagine what 20 years of peace would have built in Afghanistan. So, Taliban are certainly morally responsible for that outcome even if the US invasion not justified to begin with ... but, of course we know ahead of time there will be an insurgency and Jihadist fighters aren't going to follow our little rule book, so US is responsible for the outcome as well on that account.
So, a useful contrast in terms of what the rules of war are even about in the first place, but also Taliban insurgency serves as a contrast to conventional warfare. The Taliban did not win a single conventional style battle against NATO, and didn't "win" in the end in any military sense, just tired NATO out essentially.
Both Afghanistan insurgency and first person shooter games, it seems to be most people online base their understanding of the Ukrainian conflict.
This basis of understanding leads to, for example, the narrative of the day that "tough guy" foreign fighters are going to arriving in Ukraine and that matters; as you just need a bunch of tough guys with riffles and shoulder launched missiles to "do tough guy shit" and win battles. The mental image seems to be that tough guys can go out with a riffle and a bottle of Jameson and "find the enemy" and shoot them.
First misconception with this mental image, is that you mostly don't see the enemy at all in conventional warfare, at least not in the sense that you can then just shoot them with a riffle.
Conventional warfare is not fought on the basis of tough guys, although they can play a role, but is mostly a positional battle between artillery and the logistics to supply that artillery. It is a "system" and not a individual first person shooters bravely fucking up the enemy.
The core thing first person shooter games lack as a basis to understand real warfare is the mortar. Of course, you could have a mortar team in a first person shooter game, but it would be insanely boring to be on said mortar team. Which is why in every single conventional battle, pretty much anywhere on the world, you will at least find assault riffles and mortars even in the poorest military engagements (at least on the winning side).
The system of mortars and rifles is already insanely more dangerous than just assault riffles, and you can't just "throw a bunch of tough guys together" and work a mortar team. It takes real training and skill on several levels.
On television we sometimes see soldiers casually dropping mortars into tubes that go off and explode somewhere, but this is not the whole "team" and, hopefully, they aren't just firing in the general direction of the enemy but actually at something. The whole process starts with an observer and his communications side-kick, who sneak around and find a target. If all goes well the observer figures out where the target is on the map, the communications side-kick then gets that information to the calculator guy, usually at the command post wherever it is but he can also be just hiding under makeshift umbrella in the rain. The "gold standard" of communication in this context is a wired line that sends (little) signals, but could also be just communicated by sneak. Anyways, the calculator guy works out the direction and the distance, takes into account wind speed and rain, and therefore the angle and additional powder / high explosives (mortars go like 20 feet with just the shotgun shell that sets them off), and whoever is in command approves the strike, and then this information is relayed to the team running the actual mortars. The actual fire team then needs to work out how to get the mortars in the right direction and angle (this is not some trivial task, and starts with setting up a guide stick as a reference direction, but sight on a mortar is not fixed in space and so moving the mortar around moves it off the guide-line which needs to be compensated for), and then the mortars are backed with powder / high-explosive required, pins removed and away they go.
Obviously, this whole process is in the context of some officer having some workable plan, we hope.
Now, the difference in accuracy between a good mortar team and a bad mortar team, and the difference in the observer (of which the whole process depends) not-getting-killed first and getting-the-enemy-killed first, and the time to setup, camouflage and setup a adequate defense of the mortar battery / escape plan, is really immense. A good mortar team can not only avoid getting killed, but can achieve the accuracy of the mortar, which on relatively short distances on a windless day can be a few meters.
Observer can also observe where rounds land and so send back corrective instructions (which are then very quick to process).
There are also other weak links in the chain such as the communications guys and calculator guys.
Point is, takes a lot of training. However, the result is that indirect vertical-ish fire can be brought down on an enemy position such as directly into their trenches. Also, mortars going off in the general vicinity (fire for effects) causes people to hide and the opportunity to maneuver or then tactically retreat.
Mortars can also fire other kinds of ordinance like anti-tank mortars, anti-other things, and giant flares that case a shadow at several kilometres. When assaulting a position at night, what feels save may not actually be safe if a artificial sun goes off overhead and you're totally visible and come under immediate mortar fire. We don't see the US using flares in an insurgency as A. they have really good night vision and so B. if would only give the opposing side an advantage. However, in conventional warfare flares are insanely useful to defend a dug in position.
The point of this long explanation is that this system takes a pretty long amount of training to use effectively and the tactical upgrade from just guys with riffles is immense.
From this basic riffle / mortar system, the purpose of bullets is mostly to pin down enemy forces to then hit them with mortar fire. Nearly all bullet firing in conventional warfare is suppressive fire for the purposes of striking the enemy position with indirect fire.
A war system then builds up from this, mostly just doing the same thing. Artillery serve the same basic purpose of mortars but against harder targets or farther away and requires the same basic info chain, and the basic purpose of air power is to both observe and substitute artillery strikes. Armor comes in precisely because the bullets and indirect fire system is so effective, sending a wave of infantry just get slaughtered like in WWI. WWII was totally different because armor can be concentrated to break through enemy defensive lines. And so, since armor is so amazing effective against the basic bullets and shells game, air power became so critical because it's armor's biggest weakness.
"Peak armor" was certainly the Nazi's invasion of France, and ever since then significant effort has been put into systems and tactics to defeat armor.
However, all these other way more expensive systems, such as planes and missiles of different kinds, is all happening at the end of the day to get tactical advantages (information and strikes of key things / critical moments) needed to make defensive lines of infantry and mortar/artillery cover (as bullets and shells are insanely cheap compared to cruise missiles and jet fighters).
The basic thing you want to accomplish in conventional warfare is surround your enemy cutting them off from reinforcements and supplies. So, in this basic strategic situation of lines of infantry supported by indirect fire, the counter is to break through the line at some point creating the problem for the enemy of either abandoning their positions and falling back to make a new defensive line (costs time and energy and gives up ground) or then risk being encircled. Hence, the counter offensive is critical to be able to deploy, but this requires armor and / or air power (who can both show up to the fight in a relatively short amount of time). You can't easily send infantry by foot to reinforce a position twenty kilometres away; the battle maybe over by the time they get there, so you need vehicles, civilian vehicles are extremely vulnerable, so you may need armor personnel carriers to even get reinforcements to the battle front requiring reinforcements.
The conclusion to be drawn from this analysis is that talk of "hundreds of thousands" of Ukrainians joining the fight may not be effective in any conventional military battle. Pretty much the only thing an untrained conscript or civilian can do is simply wait in a trench or some urban trench-like location for the enemy to arrive.
Hence the pumping in of ATGMs and Manpads which can be used by infantry individually with even minimum training, and does not require a coordinated team. However, these weapons can only slow the enemy as they are great to ambush armor, causing losses and caution, but they cannot really be used to assault a infantry line (insane waste of money) nor can do anything about relentless shelling of your own infantry positions, and, without good logistics, ATGM's may run out in a given location allowing the enemy to break through with armor that then no one there can do much about.
