Professionals discuss logistics. You all know this saying which is ultimately true. Russian Armed Forces today celebrate a Day of Rear Services (and Logistics). It is a huge universe of crucial supply services, from ammo and fuel to food and pay, which also has its own War College--Academy of Material-Technical Supply named after Army General Khrulyov. No armed forces in the world can fight without rear services, which also, as was the case in WW II ended up being not so in rear and very often in the very center of heavy fighting. So, here it is--a good army (and navy) are only as good as the provisions delivered to them by logistics.
