The convoy mission, my way

[Stix]

Hi.

Thanks for your help, I didn't thought about flanking from there...

BUT. Now my problem is a shower of nades on my guys.
Ennemies have; better weapon, better skills, number,... And their nades are always right at the bad place for me. (while my nades always fail because of my own cover)

Well... I'm on this mission since 3hours, doing and doing again... I'm thinking I don't have the level for this; my guys are very bad and when I see you weapons on your screenshots, I guess there is a problem: I only have
1st character: a snipe rifle (something v700) + colt
2nd character: mp5 (red dot + silencer) + silenced pistol

Damn it. I'll have to come back, and to do other missions to get better equipement, right ?

Damn.

Spent so many hours on this mission...
Now I finally made it, but... these silly soldiers are all dead !!!! My stupid guerrileros are ALL dead... I'm bored by this mission.
How can we do it if friendly troops runs everywhere.

I guess you know this, but just in case: you can actually throw back grenades (at least those that are timed) as long as they land right near your guys. Its no fun when they explode in their hands, but worth a try.
If they have to move to pick it up though, or in worst case, already doing something, like aiming, than you are better off sprinting (if they are standing) or going prone and rolling away (if at least kneeling).
And for early completion of this mission you can use the same grenade shower since they are awesome to distract enemies, which includes them not throwing their nades at you.

That makes it somewhat hard indeed. However on the good side, that means the enemies have worse armament and armor too (unless this mission is hard-coded, which I doubt). That sniper rifle is probably not the best here unless used by a high level guy (such as Sniper) for far away headshots. Its powerful, but slow, so its not really worth body-shooting with it in this situation. But then again, headshots require a good merc especially when bullets fly around.
The MP5 isnt bad though. I take it you are with the rebels, so just sprint close but to some cover (like that pack of trees near the trucks, or the trucks). If you get shot on the way, load and send a few burst shots in their direction (forget about hitting them as long as the shots are close its fine) before the rush, however you are best off sprinting straight at start before they take position/aim.
Once close enough, throw in some nades (3-5) with high throw (again I guess you know, but you can arm then throw them directly from your pockets), then jump out of cover and start shooting from the hip, if you did it right the army guys will be running around wild trying to avoid the grenades and wont care about you. Just make sure you reach/make a safe place by the time the nades exploded or you will be in trouble. Or if you are confident, you can keep pushing of course. But if you wait a bit out of their sight, they will hopefully start shooting the guerillas instead (or throwing nades after you, so be ready to run), and you can run out/shoot some/run to cover before they could aim at you. Prioritize guys with SMGs/pistols as rifles are too slow to get you here.
Also, since everyone in the game is right-handed, make it a habit to go around every obstacle (like the trucks) counter-clockwise if possible, giving a good chance to be able to shoot at enemies who in return can only shoot the obstacle.
While you are at this with the MP5 guy possibly drawing away the attention of most soldiers, the other merc can happily keep sniping, and you can also expect the guerillas to land a few lucky shots.
Of course you can keep throwing grenades later too to flush them out from their cover, provided you brought enough. Same goes for ammo, be ready to use a lot, 2 extra clips is a minimum (not boxes, clips).
And a tip for early fights: since Im quite sure you dont have a vehicle, and instead carry around backpacks, drop those ASAP during the battle, it saves you a lot of stamina and you shouldnt have anything in them that you need during the fight anyway.
