So, working on long war team strats. (currently on fishing village mission, going well so far and... 3 zombies and 9 chrysalids dead? Will finishs it tonight probably, but while I am away from the comp...)
There seem to be lots of fun less-than-obvious strategies to pull here.
Strat one "Get Over Here"
Gunner - Suppression, Flush, Shredder, Danger zone, Ready For Anything Bring em On, Sentinel
Scout - Lightning Reflexes, Holo Targeting, Flush, Ranger, Smoke and Mirrors Lock And Load, Vital Point Targeting
Infantry - Light em Up, executioner, opportunist, aggression, Sharpshooter, Sentinel, Vital Point Targeting
2x Assault - Run And Gun, Close Combat Specialist, Aggression, Close Encounters, Ranger, Sprinter
Scout - Lighting Reflexes, Flush, Lone Wolf, Ranger, Aggression, Squad Sight, In the Zone
So this team is built around the wonderful and versatile ability "Flush", which is a super-accurate attack the forces the enemy to move out of cover, and all the ways to abuse it.
First up, and the obvious easy bit, is the one-two punch of a gunner with Flush, Shredder, and Ready for Anything. This allows you to get in a super accurate hit followed by a full attack against an enemy out of cover. Getting them to sentinel means you get TWO attacks. Obviously you want to give this guy an LMG for maximum damage and good suppression options.
Next up you have a pair of assaults tailor made to wreck the heads of flushed enemies. Move them in, get your free attacks, flush the enemies that survive to get MORE free attacks, potentially against several enemies since you have plenty of people on your team to flush. If the enemy avoids getting wrecked, its probably because thhey fell back, leaving your pushed up assaults relatively safe.
Infantry is a geat flush supporter. Launch an attack against whoeve, maybe finish off the first guy you flushed, then drop into overwatch, and get two high crit chance high damage reaction attacks. Three shots in around, with a very high chance to crit? Yes, pkease.
You have two scouts here - one is probably the one you'll lead flushing with, and the other is there to clean up the mess. Remeber flush is super accurate! Great for picking off low health enemies, and aimed with a marksman's rifle they should be well equipped to clean.
Throw a Shiv in there with HEAT ammo to provide a convenient target and to help finish off shredded robots right quick (flush pretty much guarantees the shred is successful), and you're golden.
