Do you mean that if I land 100 small troops, which have sensors with offenses +10, and in the same transport are 100 assault infantry, with offense +20, then ALL the units will have offense +30?
Or will the bonus of every single unit stack up to....+6000 .

It can't be like that, right?

It depends on where the bonuses are. IIRC there are three possible locations. Putting the bonus on the troop chassis itself DOES cause a stacking effect for that bonus only. See Proportions Elite Infantry for an example - each one present will add a +1 to-hit to the entire army.

Combat Offense bonuses don't stack but DO share - the highest one of any in the army will be used for the entire army. Proportions and unmodded combat sensors and ECM are examples of this.

To-hit bonuses on weapons neither stack nor share. By this I mean the to-hit bonus of the weapon's attack itself. I don't know of any unmodded (or modded) weapon that uses this except in Proportions mod - see the infantry weapons there for an example.
