I've noticed some inconsistency in a field of HE kill of hand grenades:

UK
87 Mills Bomb - HE kill 5

France:
87 Hand Grenade - 6

Soviet Union
87 F-1 Grenade - 3

Germany
87 Handgranate - 6

USA
87 Mk. II Grenade - 5

Poland
80 Granaty - 3
81 F-1 Grenade (Soviet) - 3
82 Grenade F1 M.15 (French) - 3
86 Granat wz.24 Ob - 8 (range 2!)
87 Granat wz.24 Za - 4

Italy
87 Bomba a Mano - 6


Information on grenades is usually scarce, but it seems, that Mills bomb, French and Soviet F1 and US Mk 2 were all similar fragmentation defensive grenades, weighting some 600 g, with some 60 g of explosive (possibly Mills bomb was somewhat heavier - I've found info on 69 g of explosive).
On the other hand, most common German Stielhandgranate was weak offensive grenade, with no fragmentation shell as a standard.

Therefore, it seems to me, that Mills should have kill=6, French, Soviet, US grenades - 6 or 5, and German - 3.
I have no info on Italian grenades, but I assume it's similar.

Only the Polish OOB makes a difference between defensive and offensive grenades - maybe a good idea, but I feel it is rather splitting a hair.
We have a defensive 86 Granat wz.24 Ob, which definitely should be similar to the ones above and have normal range 1, and an offensive 87 Granat wz.24 Za, which also has too much kill (4) for a thin shell.
There is also generic 80 Granaty with kill=3, used only by some bunkers. Weapon 82 Grenade F1 M.15 should be equal to French defensive grenades.

Anyway, I suggest to rename Polish 86 Granat wz.24 Ob to "Granat obronny" (=defensive) without detailed mark designation, especially, that basic Polish defensive grenades were wz.33, introduced in 1933 only. Similarly 87 Granat wz.24 Za could be renamed to "Granat zaczepny" (=offensive). "Ob" and "Za" are not valid abbreviations.

Edit: further suggestions as for Polish grenades are in a appropriate thread.
