Yeah, sure. The M113 in all its versions is combat-proven and the most successful tank ever built. But you know better, of course.
The sherman tank and Sopwith Camel are both combat-proven. Doesn't mean I want to roll around in them. If you need tracked capability get a Bradley if you need wheels get a Stryker. I did 50-60 miles worth of route clearance missions a day in a Stryker. If I tried to do that in a M113 I'd probably throw a track once week. In terms of survivablility anything that can take out a Stryker (large burried IEDs, EFPs) will take out an M113.
And who the fuck calls them "Gavins"? I have never heard that word come out of the mouth of a sapper.
