Generally most dismounted squad/sections are in the 10-14 personnel size now.
Which puts a Platoon in the 40-56 size. For Light forces this makes sense due to the need to rely on internal firepower, support, and initial casualty care/evacuation, but at the end of the day it really is simply ensuring that the Squad/Section and Platoon remains combat effective after sustaining a few casualties.
The issue seems to occur when one starts thinking about Mechanized Infantry - what are the dismounted personnel losses to the section/squad that one will accept in order to crew the vehicles.
One may want to dive deeper into the mechanization, where I make a break with a Mechanized force in terms of a tank/infantry integral force, and where I see wheeled light armor. Mainly as off road mobility like breaching, and assaulting an objective is heavily skewed to tracks. Hitting a trench in a LAV is not fun (been there got the T shirt, admittedly it was way way worse in the AVGP). The weapons on the vehicles are vastly superior to what soldiers can carry in terms of firepower and FCS, and if every situation one could guarantee vehicle support, it would reduce the need for a lot of the heavier weapons that dismounted forces carry
Certain dismounted tasks require large numbers of troops, this is where the Bradley and similar IFVās with low dismounts tends to falter. Urban combat, clearing or combat in any sort of complex terrain is manpower intensive.
Looping back to the comment I started with of dismounted Squad/Section and Platoon sizes, it really doesnāt matter how the soldiers arrived at a mission, certain tasks are going to require the same number of personnel. The physical act of clearing a wood line for instance will still require X bodies regardless of who does it ā however the security, overwatch, and medical personnel needs may be decrease by a number if those tasks (or portionās thereof) are able to be accomplished by vehicles and crew. Subterranean clearance however the vehicles and crews will not add much value.
I like 12 for the Section/Squad size, simply because 6 is now generally seen as the minimum size for a detachment to operate 24/7 for a period of time in combat. Now it could be 10 +2 atts, depending upon mission - but simply for the dismount tasks I like 12.
Now in my ideal world one would have a tracked IFV, and wheeled APC that would allow for crewing the vehicle (3) and 12 dismounts, with seating room for 2 more, and floor room for 6 others in extremis.
Letās say a CV90 type vehicle same height and width with probably 4 more feet in length. As much as I like the AMPV, with a turret it is enormous. Down here the US Army has played with a number of different Bradley Platoon and Company arrangements. Trying to raise the number of available dismounts for the Platoon (and thus Company and Battalion). Also the Infantry request was for OMFV (now MICV) to have 12 dismounts from the lessons learned that the Bradley didnāt have enough dismounts in combat.
Iām of the opinion you can have a lean formation at the top of the pyramid, but depth on the base is very important). So the 2 Maneuver Brigade, Division structure is very workable, as long as the Squad/Sections, Platoons and Companies are sufficiently sized.
@FJAG Bradley platoon organization has been all over the map, from 6 man squads plus an ATT to the various āChinese Firedrillā cross loaded vehicles, and since 2019 they have war games out 6 and 8 vehicle Bradley platoons
Iām much more in favor of more vehicles/platoon than less, but also having some āroomā in the vehicles for cross loading in combat if there is a non catastrophic vehicle casualty.
