Recommend me a faction/battlegroup for 1v1-only?

There's one thing I hate playing 1v1: the 'whack-a-mole'. 1v1 maps are relatively big for 2 players, so it's very easy for either player to just send cheap throwaway units to constantly uncap points in the backline (doesn't even matter if there's an MG there, they can usually uncap before getting pinned).
So then you have to send a unit to recapture the point. But then the same thing starts happening on the other side of the map. And the game devolves into this constant cap/uncap bullshit, and it's just not fun, hardly what a WW2 RTS simulation should be all about. (Expert AI also does this a lot)

Which faction/battlegroup is most well-equipped to directly counter this sort of thing?
