There may be some training of 'troops' by sending them into burbs to collect food for the handout gaggles, but the ultimate reason for the ammo and vehicles is to deal with what is left AFTER the designed collapse runs its course. How do we know this? ... The fedzilla orders of several years of ammo means they know there is coming a date certain when resupply of ammo for their weapons will be suspended during the lawlessness and collapse.
We live in interesting times. Let us hope that Justice breaks out. Justice for all.
