Repair and Replacements Review

[gsparks3]

Running a review of the Master Repair Table (Campaign Operations, p. 205-207) for missing, inconsistent, or confusing items (both in the table itself, and any issues in MekHQ versus said table). This issue will be updated as I investigate further.

• [ ] Mech cockpits can take critical hits or otherwise become damaged (e.g. by ejection), but have no entry for replacement or repair. They do have a cost listed in TechManual (p. 277). MekHQ currently uses non-canon values for cockpit replacement/repair times and TNs, since canon ones do not exist. It is possible they are intended to be covered under "Weapons and Other Equipment", but all other required mech components (engine, gyro, sensors, life support, actuators) have dedicated entries. A CGL ruling will likely be required here.
• [ ] Both the Replacement and Repair tables for Protomechs list "Other Critical Hits" as an entry, but in the Diagnosis section there is no indication of how to determine whether a Protomech non-weapon critical hit (e.g. arm/leg crits) may be repaired or if they must be replaced instead. They may be considered covered under the "Weapons and Other Equipment" procedure, since on cross-checking with the Mech diagnosis entries, there is no specific entry for actuators there either.
• [ ] Both repair and replacement entries for Protomech "Other Critical Hits" list up to three hits; it does not appear possible for any Protomech location to suffer three critical hits without the location being destroyed and requiring location replacement (a different entry in the table). The "3 hits" entry can likely be removed. Both 1 and 2 hits are valid.
• [x] It is unclear when the "Motive System" entry in the Vehicle Replacement table would ever be used. Motive crits are possible but covered by the "Motive System Hit" Repair entry, and there is no indication that the motive system ever becomes unrepairable under Diagnosis. Resolved: Replacing a Motive System only appears necessary if an Elite team fails a Motive System Hit repair, rendering the motive system completely unrepairable.
• [ ] Vehicle Diagnosis lists a possibility that weapons or other equipment may be repairable instead of needing to be replaced, but the Vehicle Repairs section of the Master Repair Table does not have a "Weapons and Other Equipment" entry.
• [ ] VTOL vehicles can suffer a Flight Stabilizer critical hit. Repair or replacement values are not explicitly listed anywhere in the table, unlike all other inherent vehicle components that can take crits. However, this may have been intended to be covered by the "Weapons and Other Equipment" entry. A CGL ruling will likely be required here.
• [ ] The Aerospace (Small Units) Replacement table has no entries for: Avionics, FCS, Landing Gear, Structural Integrity, Thruster, or Bay Door. Entries for these do exist under the Large Craft heading, but the times are quite long (as appropriate for such large units) and different values should likely apply for non-Large Craft, especially Avionics/FCS/Landing Gear/SI on fighters and fixed-wing support vehicles.
• [ ] The Aerospace (Small Units) Replacement heading does contain entries for Gyro, Jump Jet, Turret, and Destroyed Location items. I am uncertain if these are intentionally included. Meant for LAMs, perhaps?
• [ ] The Aerospace (Large Craft) Replacement heading contains an entry for CASE/CASE II. DS are explicitly disallowed from mounting either, and I cannot find anything that indicates that other types of Large Craft can mount any type of CASE (the TO:AUE entry for CASE II only lists BM, IM, ASF, CF).
• [ ] The Aerospace (Large Craft) Replacements table lacks any entry for "Other Equipment" (covered in most other categories by "Weapons and Other Equipment", which for Large Craft is merely "Weapons").
• [ ] For some reason the Fuel Tank (Fighter) Replacement entry is under Large Craft, when it should probably be under Aerospace (Small Units).
• [ ] Repair times for all Aerospace units (large and small) are combined into a single heading, which causes similar issues with relatively long repair times for Avionics on smaller units. However, the repair times for the other items applicable to non-Large Craft are actually still fairly short and can likely be left unchanged.

It is unclear when the "Motive System" entry in the Vehicle Replacement table would ever be used. Motive crits are possible but covered by the "Motive System Hit" Repair entry, and there is no indication that the motive system ever becomes unrepairable under Diagnosis.

Would that apply to a failed repair check (by elite tech failing, or margin of failure) that destroys the item or renders it unrepairable by others?

Hmm. Failed repair checks don't destroy the item (only failed Replacement checks do, and only the part you're currently installing), but they do render whatever damage was supposed to be repaired unrepairable without outright replacement. So a failed Motive System Hit repair by an Elite team means you either live with it or replace the entire motive system. That does check out.

A gyro swap is supposed to be Class D, but appears to be Class F in MekHQ.

This issue is only for repairs and replacements of items in a specific design, not refits, although the refit data in MekHQ being outdated was another long-standing issue and it's good that you got it updated.
