Lost Battalion mission

[Sawboss]

Hi folks, so i need to ask... is this mission supposed to marked as a yellow mission? I just tried twice and got one shotted from just under 900m the first time using my humvee for cover, the second time i changed position and i was prone hugging a rock from around 750m using a suppressed weapon and this is after tasking out the sniper in the group first, which means im getting hit my an assault rifle (most likely). Both times i manage to take out 1 ai, and a split second later im dead. I do yellow missions all the time with mostly no problem so im wondering if this is meant to be a red or grey mission?

its a default mission so i could check the actual level of it>
7-9 AI with random level and random type so it could end up pretty tricky if they came out assault/sniper on hardcore, thats the trouble with some of these default missions.
I am trying to write individual missions which are the level they say are
