Brian,
I just noticed that polish wikipedia gives an extremly detailed breakdown of the Warzaw Motorised Brigade.
According to the article a motorised squadron had:
4 officers and 116 men, divided into three platoons each of four squads.
Equipment: 10 pistols, 14 LMGs, 3 ATR, 93 rifles. 1 terrain car, 5 MCs with sidecars, 2 MCs, 11 transport trucks and one kitchen truck.
It list a fair number of sources so it should carry some weight on the issues, although i would not be surprised if there were some differences between the two motorised brigades.
