From CFJP 4-0, the four lines of support are:There have been discussions about where commercial service providers can inject services to deployed operations or which is the most forward line of support that civilians can deliver. From an Army perspective (maybe not from a navy or air perspective), the cut-off is the operational to tactical divide. The divide is at third line by the definitions above, and it will probably always be at the JTFSC.
- For a BG deployment with an FSG that is a sub-unit of the JTFSC, the operational divide is internal to the JTFSC with the FSG reaching into the tactical level while the remainder of the unit is operational. In this case, civilian delivery could go direct to the second line (JTFSC).
- If Canada deployed a land formation, the operational divide would be between the service battalion and the JTFSC. In this case, civilian delivery could go direct to the third line (JTFSC).
- In the improbable event of a major conflict with a deployed Canadian Corps, the Corps could be an operational level HQ and civilian delivery might bypass the JTFSC for delivery to the Corps Support Command (COSCOM) ... but don't expect we will ever see that.
Generally, I agree. Any changes to CAF logistics must support all environments. But, change should not be contingent upon unanimity across the L1s. The CDS and VCDS can give orders to move in a direction that is best for the CAF, even if it leaves someone a little grumpy because new ways of support are not that person's comfort zone.
I think it might be easier to understand the problem if you try to answer (and quantify) what is a Day of Supply. The question has been asked before including by Col Conrad (who has already been referenced in this thread). Some things are easy to quantify. If you know the number of soldiers, then you know the number of breakfast, lunch and supper required. But for most everything else (including consumption requirements of spare and replacement parts to equipment casualties) the enemy gets a vote. For ammo, 1 DOS must be greater than the average day's consumption because, if your unit only carries what it will consume on an average day, you can expect to run-out often. Is your 1 DOS based on the 95th percentile, so you only expect to run out of ammunition about five days in every three months? That still seems too often to accept.
We need our supply system to have the capacity to meet the spike demand and the surge demand (a spike with endurance) that we were unable to predict on a calendar. We cannot consume ammunition at a rate to sustain war time production levels without a war, but the multi-year stockpiles gives us a large quantity of nebulously defined DOS so that we can fight while industry ramps itself to wartime production. At a national level, we could reduce the age of our stock and increase capacity of our peace time ammo production by doing more range training with live ammo (less simulation), but I don't think we should start shooting at our trucks to increase the demand for peace time parts production.
