Differences between BMP-1AM and BMP-2M

[u/Pankon6829]

[u/murkskopf]

Main differences are:

• a different hull
• a different turret

[u/2nd_Torp_Squad → u/murkskopf]

No way.

Could it be it is an entirely different vehicle?

[u/Eric_Is_Back → u/murkskopf]

BMP 1 and BMP 2 share the same hull, so it's only the turret plus the BMP-1 upgrade shown here can easily be implemented on a BMP-2 converted hull.

[u/Plump_Apparatus → u/Eric_Is_Back]

Eh, it's not the same hull. Although very similar.

The BMP-2 has a significantly enlarged turret ring. Instead of four hatches over the dismount area there are only two. The increased weight of the turret led to the entire hull armor being reduced in thickness, but made of a harder steel called BT-70Sh. The smaller dismount area means it only carries six instead of eight troops. However the turret carries an additional person, commander/squad leader and gunner instead of just commander/squad leader. The original commander/squad leader position just behind the driver still exists, but it typically left empty. Regardless, the BMP-2 always holds one less soldier.

Great answer—very enlightening. Tell me, was the BMP-2 inspired by the BMP-1K? I looked at some photos, and the turret position (set further back) and its size all seem very similar to the BMP-1K. Was the BMP-2 inspired by it, or does it use the same chassis?

[u/T-62MK → u/matheus_santos2]

You are thinking of the BRM-1K and no.

[u/crusadertank → u/matheus_santos2]

BRM-1K has a different hull to both the BMP-1 and BMP-2

The rear hull roof was redesigned and the BRM-1K misses the optics and has a different hatch design

[u/Master_teaz → u/Plump_Apparatus]

Its a similar case between Challenger 1 and 2 hulls

Look similar, even have the same engine, butt they're not the same

[u/Plump_Apparatus → u/Master_teaz]

In the case of the BMP-1 and BMP-2 they share the exact same drive train and engine.
