I have learnt that both Corps don't have any Ind. Arm. brigade. You are welcome to make corrections.
Out of 49 arm. regiments in PA,
It is understood that 2 Armoured div's have 12 arm. regiments but no MIB's (mechanized infantry is provided by 2x partly mechanized divisions in each Corps), 2 Mech. div's have 10 regiments with own MIB's, there are 8 ind. arm. brigades (with 16 regiments). Plus 2 Ind. Mech. brigades with 2 arm. regt, How are the remaining arm. regiments distributed among Inf. div's? And, which inf. div's don't have them (besides FCNA, 12 ID, 19 ID, 34 Light ID, etc).
