Things get even more interessting if you try to get your tank and the enemy into one picture:
Leopard 2A4 in position, enemy is at 12 o'clock
You see: nothing.
If you switch to 8x magnification, you see them, but your own tank would be to big for the picture.
In the gunners primary sights(GPS) you get a good view, and might even identify them a T-tanks.
Distance to target is 2220m, which is considered a standart engament range.
And that my friends, is why tankies usually just laugh if the infantry speaks about "long range engagements" :-)
