Wouldn't the new tripod/Mengshi mounted ATGM make more sense at the battalion level? (HJ-16)
Given HJ-10 is brigade level.
HJ-12 would in turn make more sense at company level.
Infantry engagement range is usually within 400m to a few meters in a close terrain. You don't need atgm with a range of 4km at company level.
Moreover missiles have to go through an initialization phase and it short range accuracy are usually lower.
When ops requires, the ATGM platoon can go on a dismounted Manpad role and tag along with the coy Movement To Contact.
Hence ATGM at battalion level should be light enough to be man portable. Readily able to switch to supporting company.
