So, during my correspondence with Josh, he mentioned how the trend of Zeon-affiliated senior officers has been to be very skilled at winning particular battles, and absolutely terrible at achieving overall ends. Other than for narrative purposes, where it makes the badguys seem more fearsome if they win frequently, but the audience demands that the good guys usually win, and even Sunrise grudgingly admits that the Zeons are the badguys, this seems like a common enough trend among all Zeon commanders & successor groups to be worth considering more deeply. It's most glaring with 0083 and ZZ, but present throughout MSG and arguably CCA, too.
It seems as if Zeon lacks professionalism among their senior ranks. Surprise! Not really unexpected when considering the senior posts go to either members of the Zabi family or to their best sycophants. This is exacerbated among even the competent senior officers like Dozle & Kisheria by family infighting & jockeying for position/power, where Dozle was unwilling to ask for support from the MAF because he was afraid of appearing weak. To say nothing of Gihren's offering his own relatives and bases on the chopping block in order to solidify his own position.
Clearly, the Principality's military never developed the proper experience with large scale operations to learn effective strategy. Their tactics were often brilliant, most notably in 0083, but they always screw up the strategy. "You may know how to win a victory, Zeon, but you do not know how to use one," to paraphrase one of Hannibal Barca's officers. The relative youth of the Principality's armed forces as an organization is doubtless the root cause. They never had the time or the opportunity to practice fighting a war until they started one, and so they went about it rather amateurishly. "Amateurs study tactics, professionals study logistics." Their officers were still developing the necessary skills to command large formations, and so while they're often good with small ones, different abilities are required between commanding a company and commanding a division, and Zeon never had the time to properly develop them. Losing a high proportion of their pre-war trained personnel at the start doubtless didn't help (it did the Federation no good, either,), making it rather WWI-ish, though the competition and politicking between the MAF and the SAF is clearly inspired by the lack of cooperation between the IJA and IJN during WWII.
Haman's Rock Zeeks are probably the most egregious in their lack of military professionalism and acumen, while paradoxically the Zeon remnants she allies with in Africa are probably the most tactically proficient group to ever serve under the Zeon banner. But while a fair number of the Principality's military personnel escaped to Axis, there's no evidence of them when the Rock Zeeks return to the Earth Sphere, as the youth & inexperience of Haman's forces is constantly highlighted by their childish actions and the ease with which they are distracted by shiny objects and/or someone yelling "Squirrel!"
The Federation, so accustomed to large formations, suffers from McClellanism, where they always want more troops and are afraid to act, but otherwise show pretty decent strategic insight, mostly lacking only the will to carry it out, prompting the more intelligent and capable Federation officers to go gallivanting to the rescue on their own.
