I would not bet against you, that sounds spots on.
And I’m clearly not up on modern TOE. But close enough for purposed of discussion.
What’s a full-strength company, then, three platoons with 4 tracks and a 2 track HQ element?
In terms of the armor, yup, four tracks per platoon plus two tracks in the HQ element. Some countries have played around with three track platoons or removing one track from HQ or both, but the ostensible standard is as stated.
Russian standard is three tracks per platoon, but they’ve been playing around with an intriguing concept for their AFVs - five tracks per platoon, where four are tanks and they work with/around a BMPT as the fifth. The BMPT: https://en.wikipedia.org/wiki/BMPT_Terminator
It’s an interesting response to urban warfare with tanks. Combined with their Arena APS it means that a platoon is going to be able to respond to and counterfire against high angle threats in urban terrain. The scenario would be this - ATGM crew launching down on a tank platoon has their ATGMs taken out by Arena, the BMPT takes out the building with its own high angle ATGM or the 30mm autocannons where the tanks can’t elevate their main guns enough.
