does not work ... landscape appears but nothing happens. Is it really a solo mission ?

After listening to the officer, nothing happens

which addons ?

Alright. I finished the mission. Kind of. I'll share the goods first.

Goods:
The mission was great, and action packed.
For extra realism, I kitted my team with 416's, Glocks, AOR1 pants and grey shirts.
I love that you used modded units and guns, great addition.
The cache was hard to find, I like that. Some people might not, but in real life you're not just gonna see a cache sitting in the middle of the road.

Bads:
At the end of the mission when I arrived at the exfil location, all but 1 of my teamates had died. I tried to call in the exfil, but I could only do it while playing as my teamate. The heli came, and I got in as the teamate, but I couldn't switch back to the main player to get him in. I'm not sure if this is a game glich or a mission glitch, but either way it sucked.

Overall, I loved this mission. Action packed, realistic, and great in general. I will definitely be waiting for more mission from you.

I think it's nice that you included mods instead of regular arma 3 guns and units. I'll try it out and tell you what I think :)
