The Infantry does have a powerful utility perk combination to improve overwatch in '''Covering Fire''', '''Opportunist''' and '''Sentinel'''.
  
 +
== Sample Builds ==
 +
===Crit Infantry===
 +
Gene-modded direct attack build on early Infantry with balanced stats or particularly high aim. Massive late game damage dealer.
 +
 +
Lance Cpl: '''Executioner''' for confirming kills. Periodically, you may want to grab '''Steadfast''' instead for your first officer candidate if they have low will, or for officers you plan on having babysit low-level troops.
 +
 +
Corporal: '''Aggression''' is the point of this build. Crit hard and crit often.
 +
 +
Sergeant: '''Ranger''' for up to 2 additional base damage per turn. '''Deadeye''' is also a good choice, as few classes can reliably hit flying targets.
 +
 +
Tech Sgt: '''Sharpshooter''' for bonus overall crit chance and for confirming kills on full-cover targets.
 +
 +
Gunnery Sgt: '''Bring 'Em On''' for damage boost on crits.
 +
 +
Master Sgt: '''Extra Conditioning''' for extra aim and survivability, especially on low mobility troops. OR '''Vital Point Targeting''' If you're happy with the infantry's movement and survivability, and would rather increase damage.
 +
 +
Equip completed build with: Standard Rifle for reliable damage. Titan Armor for good mobility troops, orArchangel armor for mobility and cover-agnosticism (getting a reliable +20% accuracy, while ensuring no melee or flanking attacks, is great!). Scope and laser sight, damage boosting or armor item.
 +
 +
No core psi talents. Take Hyper Reactive Pupils or Depth Perception (even better flying aim), Adrenal Neurosympathy (kill things early in a fight to improve the efficiency of rest of squad).
 +
 +
===Fire Support===
 +
Overwatch Control/Support build on infantry with at least good base aim (especially those with high mobility). Dominates until late game, when high-HP enemies can eat both overwatch shots without dying and high enemy defense makes the hits less reliable.
 +
 +
Lance Cpl: '''Covering Fire''' as a core perk, increasing overall aim and overwatch efficiency.
 +
 +
Corporal: '''Opportunist''' as a core perk, making overwatch shots on grounded moving targets strictly better than standard shots (target doesn't get cover), and all other overwatch shots equivalent.
 +
 +
Sergeant: '''Deadeye''' is probably the best choice on higher difficulties, as an Overwatch Infantry is often your only real defense against floaters that charge in to flank your troops. '''Suppression''' is ok if you lack other troops with good suppression builds, since you'll get a guaranteed opportunist reaction shot if the target takes any action, but very ammo intensive (2 shots for suppression, 3rd for reaction shot). '''Ranger''' will increase the damage output and help increase the odds a reaction shot will be a kill shot.
 +
 +
Tech Sgt: '''Lock N' Load''' as a core perk, allowing at least two shots per turn regardless of ammo state once Sentinel is unlocked.
 +
 +
Gun Sgt: '''Sentinel''' as a core perk, allowing three shots per turn when firing as first action, two shots after a move/reload.
 +
 +
Master Sgt: '''Vital Point Targeting''' is acceptable if you are content with your trooper's will and mobility and are ok with potentially losing them to a crit. '''Extra Conditioning''' for the added stats will help with survivability and mobility if these are lackluster by this point and the extra 4/dpt is negligible for your squad makeup.
 +
 +
Equip completed build with: Heavy Rifle weapons for bonus damage (standard rifles are fine too, especially if you take vital point targeting at MSGT). Archangel for mobility/toughness, or Titan with decent mobility. SCOPE and damage boosting item or armor.
 +
 +
Support/passive Psi talents recommended (Inspiration, Feedback, etc.), as you'll mostly rank up psi for the ability to safely use neural gunlink late in progression, and will be overwatching at end of most turns with enemy contact. No core gene mods, apart from one of the eye mods if available.
 +
 +
===Tank Infantry/Officer===
 +
''Suitable Recruits'': Unlike many Infantry, this build does not focus on taking regular shots, so high Aim is not so important. High Will is good as these troops make excellent officers. Above average Mobility will help with all the heavy gear they tend to take. High Health is preferred. Low defense, as the idea is to attract fire to these soldiers and absorb it, not be impossible to hit in the first place.
 +
 +
LCPL: '''Steadfast'''. Since this unit is designated to be the one most likely to be shot and hit, preventing panic on it not only stops its own panic, but cuts off panic chains (where other soldiers panic at each other's wounds, death and panic) at the source. Make the Infantry an Officer and the whole squad can get the benefit of the +5 Will bonus too, reducing the threat of enemy psi and intimidate.
 +
 +
CPL: '''Will to Survive'''. Key perk which lets the whole build function. Added to the DR from cover, the soldier can prevent the first 2 or 3 points of damage from each hit. Other sources of DR (e.g., officer bonus, Titan Armour, Iron Skin, Reinforced Armour) can make the unit immune to anything short of critical hits and/or heavy weapons fire. On top of this is a further +3 Will.
 +
 +
SGT: '''Suppression'''. Suppressors get fired at a lot, but this soldier is designed to be fired at. Unless there's an opportunity to end the engagement, Tank Infantry should be suppressing the biggest threat (or the second biggest threat if a Gunner is also suppressing) in every turn of combat.
 +
 +
TSGT: '''Lock 'N' Load'''. Lets the Infantry maintain continual suppression and not miss a turn of effective action.
 +
 +
GSGT: '''Resilience'''. Rounds out the tank build by preventing critical hits, reducing the threat from flanking attacks and destroyed cover too (the big weakness of Will to Survive only).
 +
 +
MSGT: '''Extra Conditioning'''. Makes for a nigh-indestructible soldier.
 +
 +
''Role'': Tank Infantry are the soldiers you want on the front-line. They should take the half-cover position (unless everyone else visible to the aliens also has full cover) closest to the alien positions (but still at mid-range). (Similarly, don't give the Tank Infantry smoke cover unless all other potential targets have equal smoke cover too.) It is more important that the cover be ''indestructible'' than low/high, as this soldier is vulnerable to cover destruction: the grenade itself won't do much damage, but will expose it to further shots against which it will have much less DR.
 +
 +
Each turn, the soldier should shoot once, and then suppress or Command, if an Officer. They are not expected to do major damage to the enemy: the shot is free and any hit is a bonus. The aim is simply to have a soldier who continues to contribute to the firefight while also providing maximum damage absorption.
 +
 +
A Tank Infantry will usually be the easiest target for the enemy to hit, and may also attract attention because it is suppressing. Some of these shots are expected to hit, but the damage taken will be greatly reduced by the various sources of DR.
 +
 +
''Gear'': Tank Infantry can be equipped with a Heavy rifle: usually, the soldier will only take the single free shot from Light 'Em Up each turn, so the penalty on shots after acting is not a problem, and the extra damage is welcome. They should wear the heaviest armor available, Reinforced Armour and another defensive item(s) to taste (Plating, Medikit, Respirator), or a scope to help them contribute to damage.
 +
 +
''Limitations'': The Tank Infantry's weaknesses include lack of mobility (heavy armor and equipment) and lack of firepower. It is the job of the rest of the squad to find the enemy threat and neutralize it. The Tank Infantry is there to weather the worst of the storm until it's over. Vitally, other soldiers must eliminate enemies, such as seekers and floaters, that threaten to flank the Tank Infantry, eliminating its cover and Will to Survive defense. Tank Infantry is not the right choice for all situations: since its offensive capacity is limited, Tank Infantry can sometimes ''cause'' there to be a prolonged firefight when a more aggressively trained/equipped soldier could have helped end the threat before it began.
 +
 +
''Suitable Maps'': Tank Infantry perform well on Roadway maps: lots of cars means lots of indestructible half-cover for both sides. They are also invaluable whenever heavy resistance is expected and the quality of available cover may be poor.
 +
 +
''Other Notes'': Note that bringing a Tank Infantry does not mean you can neglect protective choices on the rest of the squad. The AI considers chance to ''kill'' as well as chance to hit, and may pass up an easy shot on the Tank for a less accurate shot on a squadmate that might do a lot more damage in the event it hits.
 +
 +
Leaving aside Mechs and SHIVs, this leaves only Assaults as competing main "tanks" or fire magnets. Assaults can get many of the same protective perks as Infantry — Steadfast, Will to Survive, Resilience, Extra Conditioning — and get more Health per rank, and can stack defensive items without as much offensive penalty.
 +
 +
Finally, Tank Infantry make excellent officers: they get +8 Will from their first two perks and would be good choices for the first Lieutenants you promote. Their battlefield role puts them front and center in the squad: those who need the Will bonus (and other officer benefits) most are likely to be close to the Tank Infantry.

Tactical Advice

Role: Medium Range Offense

Infantry are mid-range damage dealers. They can fire twice per turn if they don't move, which makes them excel at eliminating enemies by attrition. Because they must remain stationary to fire twice, they tend to perform best with assault rifles rather than shotguns, which are more position dependent - if you want a more mobile soldier who's designed for mobility and getting flanks, look to the Assault class. Infantrymen's ability to fire twice per turn makes them competitive with Snipers at direct damage. Due to their high fire-rate it is very important to keep an eye on the Infantry's ammunition, as it can run out very quickly.

Infantry have decent aim progression and have relatively uncomplicated builds - they have at least one talent at each rank that improves their proficiency with their primary weapon and also have a selection of defensive abilities available at each rank. The Infantry does have a powerful utility perk combination to improve overwatch in Covering Fire, Opportunist and Sentinel.

MSGT: Extra Conditioning. Makes for a nigh-indestructible soldier.

Role: Tank Infantry are the soldiers you want on the front-line. They should take the half-cover position (unless everyone else visible to the aliens also has full cover) closest to the alien positions (but still at mid-range). (Similarly, don't give the Tank Infantry smoke cover unless all other potential targets have equal smoke cover too.) It is more important that the cover be indestructible than low/high, as this soldier is vulnerable to cover destruction: the grenade itself won't do much damage, but will expose it to further shots against which it will have much less DR.

Each turn, the soldier should shoot once, and then suppress or Command, if an Officer. They are not expected to do major damage to the enemy: the shot is free and any hit is a bonus. The aim is simply to have a soldier who continues to contribute to the firefight while also providing maximum damage absorption.

A Tank Infantry will usually be the easiest target for the enemy to hit, and may also attract attention because it is suppressing. Some of these shots are expected to hit, but the damage taken will be greatly reduced by the various sources of DR.

Gear: Tank Infantry can be equipped with a Heavy rifle: usually, the soldier will only take the single free shot from Light 'Em Up each turn, so the penalty on shots after acting is not a problem, and the extra damage is welcome. They should wear the heaviest armor available, Reinforced Armour and another defensive item(s) to taste (Plating, Medikit, Respirator), or a scope to help them contribute to damage.

Limitations: The Tank Infantry's weaknesses include lack of mobility (heavy armor and equipment) and lack of firepower. It is the job of the rest of the squad to find the enemy threat and neutralize it. The Tank Infantry is there to weather the worst of the storm until it's over. Vitally, other soldiers must eliminate enemies, such as seekers and floaters, that threaten to flank the Tank Infantry, eliminating its cover and Will to Survive defense. Tank Infantry is not the right choice for all situations: since its offensive capacity is limited, Tank Infantry can sometimes cause there to be a prolonged firefight when a more aggressively trained/equipped soldier could have helped end the threat before it began.

Suitable Maps: Tank Infantry perform well on Roadway maps: lots of cars means lots of indestructible half-cover for both sides. They are also invaluable whenever heavy resistance is expected and the quality of available cover may be poor.

Other Notes: Note that bringing a Tank Infantry does not mean you can neglect protective choices on the rest of the squad. The AI considers chance to kill as well as chance to hit, and may pass up an easy shot on the Tank for a less accurate shot on a squadmate that might do a lot more damage in the event it hits.

Leaving aside Mechs and SHIVs, this leaves only Assaults as competing main "tanks" or fire magnets. Assaults can get many of the same protective perks as Infantry — Steadfast, Will to Survive, Resilience, Extra Conditioning — and get more Health per rank, and can stack defensive items without as much offensive penalty.

Finally, Tank Infantry make excellent officers: they get +8 Will from their first two perks and would be good choices for the first Lieutenants you promote. Their battlefield role puts them front and center in the squad: those who need the Will bonus (and other officer benefits) most are likely to be close to the Tank Infantry.
