My impressions so far:
1. You can buy replacements via the replacements card. When you buy the card, the replacements are immediately spawned at the highest ranking HQ that is closest to the map entry point of the replacements. You can immediately see the elements in the HQ unit.
2. At the start of each turn, elements are shifted from the highest ranking HQ(s) via the subordinate divisional and briagde HQs to the requesting combat units. This movement is automatic (and according to the manual also generates traffic points on the roads). Check out your replacement reports to see which units have received replacements.
How do units request replacement elements?
All units except battle groups have a TOE (table of organisation and equipment), defining their ideal paper strength and composition. If a unit is below its paper strength, it requests replacements accordingly at the start of each turn. You can check out what a unit is missing and requesting in the unit tab ("replacements"). Also note that the size of the bar on the right hand side on the counters indicates the strength of the unit compared to its TOE/ideal paper strength (the color of the bar indicates the current readiness of the unit). Note that a unit can only request up to a certain number of elements per turn. So a unit that is at 50% paper strength can not recover completely in a single turn, even if there are sufficient replacement elements available at your HQs.
By changing the standing orders of units, you can set your units' (and subordinate HQs!) priorities for replacements. You can find the priority setting in the unit tab under "standing orders" / RPLC.
Note that battle groups have no TOE, so they're never missing elements and never request replacements. If you want to reinforce a battle group, you need to merge it with another unit. (For battle groups, the bar on the counter probably represents base combat strength? Note that a battle group that falls below 50 power points suffers an additional malus in battle)
If you set an HQ to lower replacement priority, do all its assigned units also go to the same lower priority? Or do i have to set each unit separately?
