@Stg
the 2nd team you encountered was coming at you from the 1st civilians. They are vectored SW Lodge to Vigny. (after I figured their waypoint out, it all made sense) They only get as far as you (Vigny) if, like me, you spend every available minute collecting every available weapon, and stashing it in the jeep. If you spent 'time' just investigating all the dead bodies, timing wise, you'd encounter them on the road past LaPassagne, or in Passagne. If you're quicker than that, you will encounter them when you investigate the hut near the first civilians which many players, including me, often miss. Where and when you meet them makes for a fascinating, dynamic game difference. Part of the magic.

I wont quote you, I would have said precisely what you have said about ammo crates.
@Thob
I am not a particularly hotshot player. Afaik, the only weapons I have ever used from crates is Larche. And now that I know M21 is available at T3 i go there. But, for me, and I trust many, many others, one huge enjoyment in this mission is planning, what-to-do-next. There is immense satisfaction in grabbing a good weapon out of a dead squad, it is a reward mechanism for bothering to attack them at all. Part of that all important player feedback that she's doing the right thing.
For starters, it's un-thematic that all these nasties are fully loaded. Most, the majority, would not have 6 pk mags. 2 would have been used up. I would be most surprised if anyone agreed with you that playing this mission without crates would be any tougher than it already is. There's an abundance of everything on any firefight. make the player work, it's enjoyable and immersive. Exception: the haystack is wondefully done. Basically Thob we have an abundance of formerly mobile ammo crates littered across the entire island, beginning at Vigny. I also had the enjoyable immersive experience of having to 'remember' where the hell an AA was located. 17 firefights ago. And had to withdraw and collect it, with all the ongoing ambushes that that entailed.
Keep the convoy ammo. It's a huge easter egg for a player.
If ammo crates cause lag, get rid of them. In fact, they are almost entirely useless since you cannot stick around to keep them.
