they do also fix the bridges if them being too weak to take the traffic for the supply lines, for almost anything, munitions and weapons are not all of it, they also need clothes, medical supplies
security is a high level issue but what security means for us plebs and for these warmongers are different things
if we see, what i think we will see maybe in our lifetimes, where the operational scope of a security system is at the level of a county or shire, a lot more of those small things that get lost in the big scale get handled
the escalation from state to federal to union level of focus of security leads to a steady decay of the small things, and the thing is that they don't actually realise something is wrong until one day the enemy rolls up and annexes it
security actually is more effective if its decentralised, even if the enemy is large, because the enemy has a scope scaling problem that the small units don't, and if they are chatty with their neighbours, it doesn't require forced central command to work
it is true, that security is the uppermost requirement in all cases, because if it's not attended to, it gets coopted and anexed and infiltrated
