US Army doesn't have a stryker.
The closest thing they have is the M2 Bradley which is amphibious in the M2A1 version they made the swim fence obsolete in the M2A2 version.
Wow. I'm sure that all of their stryker brigades would be surprised to hear about this.
Wow I retract my previous statement. A lot has happened since I was a M2A2 gunner.
Guess they got tired of inexperienced drivers throwing tracks on them.
