Proper Charlie

I'm getting this problem basically every time I play in multiplayer, often within a few minutes of joining. It's annoying in planes, but makes Combined Arms unplayable. And to confirm, I have disabled all the Radeon app's overlay options.

The Su-25T has the Kh-58 ARM.

If @Hags or anyone else wants a workaround until the fix is properly released, this worked for me (thanks to Ralgha for the suggestion): Open the mission in the Mission Editor ([DCS install folder]\Mods\campaigns\The Museum Relic\MR campaign 1.miz) Zoom in to Anapa airport and find the black circle around it (the airport's capture radius) Add a Red faction ground unit roughly 100m outside the black circle (e.g. a Russian BTR-80) Give the unit a waypoint roughly 100m inside the black circle Start the mission (you can't save missions from campaigns, but you can play them directly from the editor) Wait 30 seconds or so, and the ground unit will capture the airport, and wake up the ground crew Complete the mission as normal (this doesn't count towards the campaign progress, but you can score it as a moral victory) End the game, go into the Campaign screen, and restart the mission from there A few seconds after mission starts, open your communications window, and select the "Other" -> "Auto-complete" option to insta-win the mission End the game, and return to the campaign screen, now updated to show you've progressed to mission 2.

(Open Beta 2.5.6.50793) In the front cockpit of the L-39C, the red and green landing gear lights are not working. The equivalent lights in the rear cockpit are working correctly, as are the lights in the front cockpit of the L-39ZA

Yep, reproducible for me too, in the ZA only; the C seems fine. The flight controls are working, but the stick model does not move. Looks painful on the wrists :-) https://drive.google.com/file/d/1XMo2ibvUSXsVZjp3R0-OrbNv6oZ6o0J3/view?usp=sharing

Minor spoilers:

It's working okay for me. Equip an ASO-2 pod in your loadout, press right-shift + J to open the cover as Britchot says, then hold left-ctrl+ space to launch two flares and one chaff.

The Mods\aircraft\Flaming Cliffs\Missions\EN\Training folder has .ogv videos for the training, but only the Su-27 still has the actual training missions.
