Well that activated CFE patch explains now everything ;)
Correct me if i'm wrong but as far as I remember the AI doesn't build any FlameThrowers in this mission so all the ones that the players encounter are already preplaced around the map and there are not too many of them.
Using the Harvs in this mission (and also on other ones) against them can be very useful (in combination of scattered infantry) and it can also be useful for other things if you think outside of the box and use Harversters as a weapon or as a cannon fodder. ;)
Glad you loved all the available GDI missions so far and I really hope that you will enjoy the Nod ones as well , indeed I plan on finishing both campaigns (and maybe in the future also the Covert Ops missions too) but I can't really tell when it will happen.

Ohh, shit right sorry completely forget i even had the CFE patch on, but as for the Flame Thrower infantry, i get the mission isn't supposed to be a cake walk, but without the ability to build humvees it feels like the only way to kill them is just keep throwing infantry at them until they die, then again maybe i just hate them cause everytime i try to use them they all kill each other, You gonna be finishing the rest of this campaign btw? played all the GDI ones today, loved them all, can't stand playing as Nod,

Glad you enjoyed the mission! ;D
Well I did design those missions to give some kind of a challenge to the player so they won't feel too easy , that's why you have to fight also FlameThrowers but it really does not make this specific mission brutal.
Also there are no Viscs in this mission so if you are using some kind of an unofficial patch that causes infantry to mutate to viscs once they step on Tiberium it's your own thingy but I don't encourage anyone to use ANY mods while playing those missions.

Great map love it! apart from the flame soldiers, there just not fun to fight, map would be better without them, and why on earth are the visceroids friendly to Nod?
