Map: Wilderness tactics?

[AlienCat]

Yeah, I forgot to take an screenshot.

I find that wilderness map is impossible when having two solider against 5 aliens.

Basically, there are no where for the soldiers to hide, and the aliens comes from everywhere.

So, what is the trick to beat this map without causalities?

Smoke grenades.

H-Hour said it...: smoke grenades.
Every member of every squad has at least one in his belt, in my games.

I make sure every member has 2 smoke nades, 2 plasma nades and soldiers likely to be in close combat carry a plasma blade (6tu insta kill). Also remember to equip with IR goggles to counter the smoke if at close range.

1)have a full squad of 8 soldiers
2)have grenades/grenade launcher
3)most wilderness maps have rocks that provide cover and/or long range sniping positions
4)clean up anything close enough with GL bursts, MG full auto, Bolter bursts, grenades
5)clean up anything unarmored at long range with laser weapons
6)at this point the aliens should be few enough that you can use medkits to heal damage done, find those few bits of cover, and shower them with laser fire until they close enough to kill with something more deadly.
