The BMP-1 should have no trouble firing while in water, the 73mm 2A28 is a low-pressure gun and fires the same ammunition as the 73mm SPG-9 Recoiless Rifle.

As for the BMP-3 i expect that it can fire it's main gun while in water.

I dont expect amphibious vehicles to go charging toward the shore with guns blazing in the face of enemy fire although thats what the USMC is trained to do.

From what I have read almost all of the most current and next gen amphibious APC's/IFV's can fire while in the water and most have stabilized guns allowing them to do it accurately.

The new Chinese IFV is comparable in peformance to the new USMC Expeditionary Fighting Vehicle and currently carries same turret as the BMP-3 and it can fire its 100mm low pressure gun while in the water and moving.

I out and out refuse to let this thread die in such a way. Therefore, I'm posting a few sexy videos full of armor porn.

CV90-40


BMP-3


If not for the lack of an ATGM system, I'd give the award to the CV90. The ability to defeat MBTs is a huge part of being able to support your infantry squad. I still give the top slot to the M2A3/M3A3.

Re: Who has the best APC/IFV?
 

bmp-3 is one of the best. they have a nbc(nucleur-biologicel-chemical) protection layer on it(like many other apc) and they are also amphibius

Re: Who has the best APC/IFV?
 

Also consider the next gen Amphib APC's like China's ZBD2000 and USMC EFV can do over 25 knots or more in the water.

Re: Who has the best APC/IFV?
 

Virtually every modern armored fighting vehicle has NBC protection, as well as almost every aircraft.

Nuclear, Biological, Chemical. Just for future information, not trying to be rude.

Re: Who has the best APC/IFV?
 

BMD-3 is also a good apc
