BMP-1's were modernized in 1991-1994. They were equipped with the same Wegmann smoke grenade launchers as T-55MS got back in 1989. These smoke screens were used in BMP-1 and BMP-1Ps models.
Modify units 028, 029:

Finally, by accident, I was able to find a picture of a PaSi XA-203 with an ATGM.

Copy unit 051 over 052 or 053 (no proof of XA-203+ ever existing)
Add weapon 165 PstOhj 83M or 169 Spike MR with appropriate number of shots (4?). Same availability dates etc.
As I served before 2002 when XA-203 was not available but I heard about XA-185 being able to host an ATGM I believe there should also be a XA-185 variant - but like I said, it's only hearsay and projection from this one picture of XA-203 with an ATGM.
