About expend all remaining TUs Button

[CoolKid]

I have been wondering if we uses Expend all remaining TUs button does it count as TU training? Coz im not sure. If this true it could be easy exploit which is a big problem

"TU Training" has absolutely nothing to do with using TU, so the only way this button would train TU is if it was purposefully coded to do so.

I see. So TU training just apply when unit walking, right? Thanks for reply

Secondary Stats

    Secondary stats increase when one or more primary actions are performed (except for throwing). Secondary stats are:
        Time Units
        Health
        Strength
        Energy/Stamina

    Secondary skill points work quite differently from primary skills: It does not matter how many primary actions are taken; all that matters is that you did one primary action (land a non-IN attack on an enemy, react to something, not panic when Morale is below 50, or use a psi attack) -- your secondaries will increase all that they're gonna. It also doesn't matter if you did more than one kind of primary action.

Why is there even a expend all remaining TU button?

It's for avoiding reaction fire. Might not want your rocket launcher guy to fire a rocket by reflex during a terror mission, say.

Ah I see. Thank you Monsieur Align.

Just to simplify, soldiers TUs go up if they hit an alien, blow a grenade on an alien, react, psy-attack an alien, or go a turn without panicing while their moral is low. It doesn't matter how much stuff they do, they either get an increase or they don't, and the amount of TUs they get is a random number between 1 and 5. Same idea for the other secondary stats.
