Плавают, плавают. С понтонами, как М113.
Я честно говоря даже и не знал что это секрет :-)
Хотя вообщем "плавают" это сильно сказано, правильнее было бы "плохо тонут" :-))
Это есть в любом источнике - берем тот-же ФАС, http://www.fas.org/man/dod-101/sys/land/m2.htm и читаем:
In addition, all Bradleys are amphibious. Early models were equipped with a water barrier, which is erected by the crew before entering the water – a procedure that takes about 30 minutes. Later models have an inflatable pontoon, which fits on the front and sides of the vehicle. This pontoon is inflated in about 15 minutes, and is continuously pressurized during operation. The pontoon is compartmentalized to provide protection against sinking in the event of rupture of the pontoon. Water propulsion is provided by tracks which propel the vehicle at about 4 MPH.
Вот так вот.
