One needs to be very cautious in accepting advice regarding recovery of disabled devices in specific circumstances as this is an area very much under the hood with minimal dev commentary. It is complicated by the fact that disabled devices result from different conditions precedent and it is sometimes necessary for the condition precedent to be resolved first before work can proceed to recover the disabled device itself.
1. No dev has ever mentioned that unit experience or unit size is a factor in disabled devices recovering.
Edit: Have found a key dev (BigJ62) comment which corrects the experience factor. The following quote is dated 22 April 2010
1. friendly base with greater than 2x supply helps and having excess support at that base plus any corps HQ in range with a leader with high admin helps.
2. unit with 1x+ supply helps
3. rest mode really helps
4. unit with high exp helps
5. no enemy in hex helps
6. temperate hex really helps
None of these are manditory but they help.
Through it all though thare are lots of randoms that determine whether or not you can repair any devices and when I stepped into the code to watch a HQ try to repair its disabled squads I'll be damned if it didn't fail one of the randoms blowing any chance of repair and this was a unit that had really good chance at it for that turn so, it is not guaranteed.
2. LCU devices will be disabled in the following circumstances
- when initially received as a replacement device
- as a result of the LCU having too high a fatigue level
- as a result of any combat
- lack of supply
- insufficient support squads
3. Both fatigue and disruption are conditions precedent in that whilst both generate their own separate (independent of the disabled device status) input into the combat algorithms, their recovery has higher priority than disabled device recovery. Fatigue automatically increases from any activity other than sitting still. The climate and weather zone has varying impact on the gain and removal of fatigue. Whether located inside or outside of a base, together with the size of the base, are also factors taken into account in determining the fatigue level of a LCU. Being on board a ship also increases fatigue. Fatigue reduction is also very dependent on the LCU itself having both adequate supply and support squads. Being in rest mode also assists. Disruption results from combat and an opposed river crossing.
What this means is that some of the factors which only reduce the conditions precedent fatigue and disruption, are only indirectly involved in disabled device recovery. This complicates the issue.
4. The two most relevant leader attributes for recovering disabled devices are admin and inspiration. Admin is indirect and applied differently by the type of unit to reduce fatigue and disruption; the HQ leader utilising the support squads whereas the actual unit leader utilising the organic unit supply. Inspiration is used by the unit leader for devices disabled due to fatigue.
5. It is important to realise that support squads are only shared when located at a friendly base.
The screenshots show a marked difference in the inspiration rating of the two direct leaders. That together with die rolls is a significant factor in the two results.
Although both units are set to receiving replacements, the OP indicated that the 65th suffered in combat. That strongly suggests that it has received more replacements than the 48th and consequently has all those disabled replacement devices to be fed into the recovery algorithms.
