Unfortunately Foxhole state's Mimetism overwrites Albedo as long as you are in that state. So I would disagree with you on that the Sapper profile is a good idea against MSV/MMS. If you could leave the state at the start of an ARO, than yes, but it's not possible.
Just think of them as an Albedo unit and CB give em the wrong fluff. I've already admitted I was wrong about Gudan. While it's stupid easy to know what they are under the camo, the cheap order makes them worth it. The Warhorse is still a bit not needed though. No one is going out their way to isolate them and if i'm in retreat something is going bad. They also don't have weapons to take advantage of getting around the BS Attack -3.[/QUOTE] They still provide order in LoL irc, they can clean e/m mines without dodge, the are not effected by EM ammo, so you can ignore E-mitters for example. All some corner cases but if you think about it, it may help here and there.
And foxhole sucks if you need to move. You will be unlikely to use an order to use it again. Pretty worthless I feel. The sniper can't be in a fireteam too. That sucks almost more. Both the Morat Vanguard and Hawkwood can be in a team. It's too bad they don't live up to their background. It's the background I really liked before they came out.
