Armour is still good against small arms fire, but for tanks the French cut back on armor for speed and below is two reasons. Updated
105mm APFSDS-T Shot C-437 Spain
The 105mm APFSDS-T Shot C-437, can defeat the standard NATO single heavy target ( a 120mm armor plate set at an angle of 60 degrees to the line of fire backed by 10 additional 10mm plates set 10mm apart ) at a range of 5,000 meters. It makes a hole, 60mm to 70mm.
A total of 120 + 100 = 220mm ( 8.66 inches )of thickness at 0 degrees or
254.03mm ( 10.00 inches ) at 60 degrees at 5,000 meters.

Set at 30 degrees gives a thickness of 440mm or 17.32 inches of armor.

It has been a while since I looked into this sort of stuff.
Also, this is an interesting read;

Mind you, this is probably standard rolled homogeneous armour (RHA), not composite armour, or composite armour with explosive reactive armour (ERA), etc. The French Leclerc is still a very well protected tank, because of those advanced materials/approaches.
Yeah, something not quite right with the figures in the quoted post.
For instance, I understand the NATO single heavy target is a 150 mm plate set at 60 degrees incidence (rather than as described).
Also, one would expect the C-437 (an older APFSDS-T round with a 5.65 kg tungsten penetrator) to penetrate more armour at 0 degrees incidence, not less than armour slanted at 60 degrees incidence (at the same range).

They needed them to roust the enemy from Manchuria!
It looks like they did not have stabilization. Must have made accurate shooting an interesting go around.

Jeepers, those Romanian boats are bristling with guns of all shapes and sizes.
