Well, that was pretty general and accepted all around the world. French however at one moment had almost identical rifle section (10 men, 5 x SMG, LMG, 4 x rifle).
Largest influences were Germany with a rifle sections being MG centric (MG was seen as main LR weapon of the rifle section, SMGs were close defense and only 3 riflemen/10 men). This changed in '70s when SAWs (M72/RPK) were introduced, replacing LMGs on 2 for 1 basis. However as soon as the war started in 1991 this was recognized as inefficient and one SAW was changed back for LMG, so we moved back to "German" type of the rifle section (this was codified in 1993. org, but such rifle sections weer used as early as late 1991).
US organizations were also influential, especially in 1954/1962 orgs, which AFAIK were quite close to the US ones. Early Mechanized infantry orgs were even more influenced by US (since they used M3 Halftracks).
Soviet plt org with 3 x rifle section per platoon was only in use in Light companies (and some variations on hill/mountain company), while there was not a single company org that did not have support platoon (except 1952 light). Soviet influence was more noticeable in 1965 and later mech infantry organizations and in section sniper/DM.
Generally compared to a most other countries (especially "potential opponents") infantry company was well armed with support weapons, but often lacked mobility, and in early years lacked radios.
There were some very interesting formations, Partisan company in particular, intended as a "stay behind" formation, for operations behind enemy lines.
Anyway, this is all going to a book that is planted in cooperation with two more authors - book will be about infantry armament development*** in Yugoslavia, 1946-1992, but we have to cover general infantry formation development also, since it was heavily driven by a new weapons (or the lack of them, which became painfully obvious in late '60s with a semi/automatic rifle debacle). ATM there is however only slightly more than 0% chance of the English version.
Since a research into that produced loads of the data, I said "why not", it is not that YPA small units TOE could be found anywhere on the net...
Overall, over 35 various semi and automatic rifles were tested, and a final one selected (M70) was 4th on the list, and at least two replacements of it were attempted.
6 different MGs were tested as a replacement for a M53 (MG42). At one moment M60 was almost adopted.
Sniper rifle debacle, leaving army to use Mosins (in then non-standard caliber) or trophy non-standard Mausers until early '80s.
Parallel program for a paratroopers (with a Stoner 63 being acquired only a few years after it appeared) , and also a a parallel program (and some separate purchases - MAC 11 among other things) for a Territorial Defense.
Plus all the exotics that a police acquired.
Generally, semi and automatic rifles are supposed to be main part, rest being divided among MGs, sniper rifles, pistols and other infanry weapons (mortars, RCLs, etc).
We do not plan on touching M48 rifle, since there is already excellent book by Branko Bogdanovic, nor do we plan on going into details on AT weapons other than some basic history, since there are a excellent articles by same author on older ones, and we can not get majority of data about development of newer ones.
