All wars are ultimately about logistics.
This is the most difficult, detailed, technical and boring bit of warfare. Likewise, and for the same reasons it is the bit of social theory that is nearly always bypassed in Marxist analysis.
But the social solidarity of armed forces derives directly from close, conscious and constant analysis of how to create and recreate that solidarity on a daily basis, and that involves the quartermasters, drivers and cooks as much as it involves artillery seargents.
To neglect the logistical metaphor means that revolutionaries are treating the entire working class (and anyone else they look on as an ally) like soldiers who don’t have to be paid, fed, watered, entertained or moved.
It’s no way to treat an army.
More than this. It’s no way to treat your friends.
