3 in total ^^, the last one is around the left corner of the map

in the forest near the river

What you get from killing the snipers was a big surprise

so i finally gave up looing for the secret since im not sure why but im just not finding them. i found one in the woods on the right side of the map but thats it. i had 9 units going up and down in a line and just nothing. are they invincible to anything but artillery? since i tried in one game to just start nuking the map in a grid pattern and still nothing. Its a fun scenario but im not sure why the units just dont show up for me... anyway hope to see more maps soon.

the ones on the left side of the map actually don't show up for me. i have put like 10 units in those woods several times and nothing shows up... ill check again next time i play this. might just see about nuking it and see if that helps. but anyway thanks

(Update), so finally got it, the secret is quite nice, still not sure why but the last unit never showed up for me. so i ended up pounding the spot with arty for a bit but the unit just never showed up oddly. besides that was definetly a good surpise

I couldn't get it to show up with recon drones and instead used a recon vehicle in the woods to finally find it.

They will not show for me

you need to kill them in order it looks like. while the last one still didnt show for me for some reason. to do this it seems you need to kill them in order. the ones near the APCs first. the ones behind the building next, last one on the left and it should work. at least for me. i tried it in a different order but oddly did not work so i assume you have to kill them in order? could be wrong tho.

the secret definitely is useful if your playing by yourself and set it to 3 players.. its honestly the only way you can win in that setting. the amount of T15s at that level is crazy and your units just cant resupply fast enough.

THX A LOT GUYS

none of the 3 units show up for me
