1.41 updates:

-Fixed issue with Long War Perk Pack incorrectly displaying hidden Squaddie abilities.

1.4 Updates:

-In the spirit of inclusiveness, I've removed the assault rifle penalties. While this class still encourages SMG usage, assault rifles may be used without drawbacks.
-To lessen the damage advantage of assault rifles when abilities and bonuses are stacked, Mark Target's bonus damage effect has been changed to a critical chance bonus.
-Found and fixed a few bugs with how abilities were providing critical chance bonuses. The sources of all bonuses should now be clearly listed when you target enemies.

Version 1.3

-Class now encourages SMG usage. All abilities that grant damage bonuses to Primary Weapons only do so with SMGs (assault rifles are still usable, however). This is meant for use with the SMG Pack mod. If there is another mod with SMGs you'd like me to support, please let me know.
-Conceal replaced with Vanish, which operates similarly, but may only be used when the player is out of visual range of enemies. In exchange, it may be used twice per mission.
-Stalker now correctly appears as your Squaddie ability. Slash has been hidden on your character sheet, though you still have the ability.
-Bladestorm has been moved to Corporal position in the Slayer tree.
-Shadowstride has been moved to the Sergeant position in the Slayer tree. Players must now decide between it and Unseen Shot, forcing a divide between melee and primary weapon concealment-retaining abilities.
-Unseen Shot cooldown increased from 2 to 3 rounds.
-Ghost-Faced Killer cooldown increased from 4 to 5 rounds. Bonus Damage reduced from 50% to 25%.
-Precise Striker bonus sword damage reduced from +3 to +2.
-Swift Blade cooldown increased from 2 to 3 rounds.
-Silent Takedown cooldown increased from 4 to 5 rounds.

Version 1.2

Bug Fixes & Ability Changes:

-Shadowstride now always grants the player -100% enemy detection radius when concealed. Added bug fixes for cases in which having other detection radius modifiers (such as on SMGs) would result in the player being detected and breaking concealment when attacking.

Version 1.1

Ability Changes:

-Stalker now grants -30% Enemy Detection Radius Reduction during concealment.
-Shadowstride now provides -70% Enemy Detection Radius (previously -80%). SMGs not longer required for -100% enemy detection.
-Mark Target now grants the Spectre (but not the squad) a 25% damage bonus on shots made with your Primary Weapon on Marked/Holotargeted/Focus Fire targets.
-Precise Striker bonus sword damage increased to +3 (previously +2).
-Swift Blade has been moved from Colonel to Captain, and has been changed into a cooldown ability. It is now a single sword attack that only consumes action points from movement and will not end your turn if you have remaining action points. It also does not break concealment.
-Sunder replaced with Silent Takedown, which is a Colonel ability. This is a melee attack that ignores armor, improves crit chance, and Ruptures the target. Any target killed with this ability puts the player in concealment.
-Default swords have had a reduction in Pierce Damage, from 1/2/3 to 0/1/2.
