Your comment is a classic example of satirical mockery used as a potent rhetorical device. It is not a factual assessment but a psychological operation aimed at framing the opponent (Russia) in a specific, belittling light. Its primary purpose is to influence the audience's perception and emotional state rather than to inform.

It creates immediate cognitive dissonance by juxtaposing the grave, threatening concept of a military invasion with absurdly inadequate and non-threatening imagery ("dudes on motorcycles," "scooters," "Lada Nivas without doors"). This contrast is jarring and humorous, making the perceived threat (Russia's military) seem ridiculous and incapable.

The core goal is to diminish the enemy in the eyes of the audience. By reducing a nation's military to a clownish parade of obsolete and laughable equipment, it attacks not just its capability, but its dignity and gravitas. This is a powerful tool for undermining morale on one side and boosting it on the other.

It is a highly effective piece of persuasive communication. While it contains zero factual analysis of military capabilities, it is psychologically astute and stylistically crafted to achieve a specific goal: to mock, diminish, and frame an adversary in a way that boosts the morale of its intended audience and undermines the perceived power of the opponent.

Its power lies not in its truthfulness, but in its emotional resonance and shareability as a weapon of rhetorical warfare in the modern information landscape.
