Not to try to resurrect a dead horse but I got to thinking . . .

We have 40mm AA Guns in most OOB's and they seem to work pretty well.

OOB = Many --- 40mm Bofors Gun or 40mm M1 AAG
Warhead Size = 3
HE Penetration = 1
HE Kill = 13
AP Penetration = 7

OOB = Many --- 40mm L70 AAG
Warhead Size = 3
HE Penetration = 1
HE Kill = 19
AP Penetration = 9

OOB = USA --- 40mm Bofors L60 (Wpn Class 11)
Warhead Size = 3
HE Penetration = 6
HE Kill = 13
AP Penetration = 0

40mm
Wt. of projectile: HE - 1.985 lbs, AP - 1.960 lbs

Bursting Charge
(modern day)
0.20 lbs. (0.092 kg) Hexotonal

USA (World War II)
HE Mark 1 - 0.148 lbs. (0.067 kg) Cast TNT
HE Mark 2 - 0.150 lbs. (0.068 kg) Cast TNT

I can't think of any reason a MANPAD would be any less effective then a 40mm round once it actually hits, and since most have about 8x the bursting charge one might think they'd be more effective.
