I doubt that AFAIK the AK203 is your standard issue which everyone gets and is replacing your INSAS while the Sigs will go to LOC and LAC and 2 Battalions in every regiment will have them because of the great response from the troops.
Yeah, they were distributed 2 battalions every regiment so the guys can get a feel of the rifle and most of them can be trained for the sig platform. You may disagree but I am super sure about what is planned. You may consult with other senior informative people on forum.
And if what you say is correct, highly unlikely though, that 72k sigs for frontline troops and still not providing scopes and foregrips to measly 72k guns compared to size of army is downright pathetic.
Changing from 5.56 to 7.62ak as standard issue, I don't think our officers have gone mad at this level as of now, this just doesn't makes sense.
Ak 203 is kinda of filler rifle in IA relegated to non infantry.
According to your info-
72k sigs for frontline
Aks for others
CQB as when needed, they will number half of ak203 ordered, so I think it already has been assigned where it need to be, which we don't know as source is scarce.
Your number data just doesn't make sense, whereas my number data makes sense, considering 1.3 million force, even if a little. You can agree to disagree, no harm intended, just in search of accurate force composition.
