I was 3rd AABN Charlie Company my whole time in. I always saw them taking test runs of the EFV across the jetty. I wish that vehicle worked out. The new wheeled one they're working is disappointing to me.
I too want to build up my vehicles, but I'm waiting till I get better at building.
I was at AVTB when they were doing the test rig and fire suppression, good times. I got assist with the curriculum for the EFV, even did some ride alongs - alongside in the 10-meter rib while I was at the school house.
I'm disappointed in the ACV that got selected, of course I'm a bit biased. The competitor ACV was an impressive vehicle, I got some stick time on that one too. Truly impressive what that thing was capable of. Quicker, provided greater situational awareness to crew and embarked infantry, had no problems maintaining speed cross-country and I got to ding targets at
3000-meters with the CROWS. No typo - 3000 - meters first round on target every time - Ma Deuce of course.
To back the LVT story up several generations, I also got to drive the LVT(A)5 Modified around. That was a beast to drive, more work-out than fun.
