Campaign mission 10 completed. Very straightforward, mission objective was to "attrite" (new vocab word!) units in the vicinity of a waypoint. There was a primary group of MBTs and a group of artillery further away. Air defenses around the target were light, just two SAMs, a MANPAD, and 3 or so AAA. The remaining enemy forces were all ~30km, which made this one of the easiest missions so far, since I had a fairly clear engagement area without having to worry about overflying other groups.
I took over SEAD for the long-range SAMs this time around (given how thoroughly my wingman had botched it last time), and climbed to ~4500m en route to the target to launch the Kh-58U. Wasn't even close to other enemy forces at this point.
Arriving in the primary engagement area, I took out the SAMs myself, then cautiously approached the remaining units, designating individual targets for my wingman. Once I was sure there was no more AAA, I gave the wingman freedom to kill stuff and we quickly mopped everything up.
At one point, an enemy CH-53E Super Stallion strayed into our engagement area, I set his engines on fire with a Vikhr, but he didn't take the hint so I gave him another one and sent him sideways into the ground.
My wingman and I still had quite a lot of munitions left between us, so we took a detour over the larger part of the enemy forces and took out a few choice targets before heading home.
I was trying to be fancy on the landing and busted the nosegear tire, but it's all good because I doubt the ground crew can hate me more than they already do.
Exit the mission and...I get a result of 75 (%?). WTF. I took out everything within sight of the target area. I was so annoyed that I forgot to note my score...
So, I load up the mission editor to figure out what I did wrong. As far as I can tell, the group of tanks at the main waypoint was worth 55 and the group of artillery was worth 20 as far as score goes, but I didn't see anything about what determines "result." (turns out that this IS result, not score, see below)
After much research online and some more digging:
- "Score" on the debriefing screen is your personal score. Everything you kill contributes to this score, apparently a certain amount depending on the type of kill. Not sure exactly how much everything counts for.
- "Result" on the debriefing screen is your accomplishment of mission objectives defined in the mission. In the case of this mission, each group of units had a point value associated with it (55 for the main tank group, 20 for the artillery group, etc).
- In this mission (and probably others), friendly losses have a negative effect on the result.
- Technically the result can be more than 100 or less than 0, but it appears to get clamped to 0-100.
- In the campaign, any result from 0-50 is effectively the same, and any result from 51-100 is effectively the same. The former is a "fail" and the latter is a "pass."
- So, there's no real reason to need a 100 on each mission other than bragging rights. In the case of this mission, in order to get a 100, I would've needed to take out at least two more groups of vehicles, which wasn't in the mission description.
Clear as mud. Would be nice if this were more obvious somewhere.

Mission 11 done. This was of the "support advancing armor" type, where friendly tanks & stuff are advancing blithely into enemy units and my job was to clear the way before they got there. The friendly advance was aiming for an airfield, with two groups of MBTs and a few other things in the way.
Based on the mission planner, the friendly units seemed to be starting off fairly close to the enemy line, so I didn't think I'd have enough time to do the "carefully work through the enemy air defenses, then mob up what's left" thing, so I was planning on taking out the enemy MBTs from max range and just letting the friendly ground forces handle the air defenses on their way through.
Things got off to a bit of rocky start on my first pass, as my first target got taken out right in front of me just as I was holding down the trigger to launch on them. Right decision would've been to either break off and come in again or switch to the SAM in that group to take it out instead. I did neither and continued closing in to take out another MBT, and drew a couple SAM shots while turning away. Fortunately nothing landed, but still, had me a bit flustered.
Frustration continued as I lost several Vikhrs to crosswinds and could see that the friendly forces were taking heavy casualties. I ended up taking one of my passes in way too close and took quite a bit of fire from APC and tank machine guns, and what I think was a MANPAD, but I'm not 100% sure because the explosion just shows up out of nowhere each time I watch the track. Also, I call bullcrap because that MANPAD unit launched at least six missiles within only a few minutes, from watching the track.
Damage ended up as a severe fuel leak and a hydraulic failure. I took one more pass in which I unloaded everything on the last couple MBTs and IFVs on the front, jettisoned the rest, and headed for home.
Hydraulic failure means drop the gear now, because you won't be able to do it later. But a severe fuel leak means you need as much speed and altitude as possible, because you have limited engine life. I dropped the gear, and split the difference on the flaps by leaving them at half. I started a full-throttle climb in this configuration--I couldn't get a ton of straight-line speed, so if I was going to make it home I'd need the altitude.
Made it to ~6000m (above overcast cloud cover) before the engines cut out, and I started gliding it in, using instruments to gauge where I needed to go in order to get there. I came out of the bottom of the clouds with plenty of altitude, but a lot closer to the runway than I was expecting. Given my previous problems losing speed on the approach and the lack of speedbrakes, I tried to do a 360 to line up for the runway, but ended up several km short (having pissed away my altitude advantage in the turn), pointed the plane away from civilization, and ejected. Sigh.
I should've done some calculations based on the distance from the landing waypoint and current altitude to determine what my target descent rate should've been. I also think that a lot more speed needs to be maintained in an engine-out landing to ensure enough energy for roundout and flare--even if I had been able to arrive at the runway, I don't think I would've been going fast enough to land gently.
Engine-out landings are something I'll need to practice. I tried to follow the track to that point so I could take control, but in ~10 viewings of the track not once did it end up that far--pretty much every time, I got an engine fire instead of a fuel leak. Oh well. I also didn't see a way to trigger a hydraulic failure in the mission editor, which would allow me to set up a similar practice scenario.
I waited around until the friendly armor groups made it to their destinations (finishing off the remaining enemy groups in the immediate area) before exiting the mission. That probably paid off, as I ended up with a 100 result.
Between my wingman and I, in this campaign we've destroyed more SU-25Ts than ever existed in real life. Don't tell my commander, he won't let me fly anymore...
Edit: Fun, next mission shows low clouds, high winds, and taking off from an airfield that's almost within range of the enemy mid-range SAMs.
