Damage dealt to small units

[ComradeP]

True, not all men/tanks/guns might be able to see the opposition. There's already some abstraction in the game as you can't be in the same hex as an enemy unit, so units are never truly hidden no matter how small they are. The enemy also fires back, which implies it offers resists the enemy attack and thus exposes itself.

The 250m hex scale does leave less room to hide in for clear terrain than the 1 kilometre scale, however.

On one hand, a small unit being able to hide and take less losses is realistic, even though at this scale its chances of hiding are not as good. On the other, the unit resists and can stop you from making progress, which makes it unrealistic that it often can't be dealt with in an effective manner that doesn't require committing a disproportionate number of units.
