I'd say this is true for most public Lakeside matches.
Depends on the situation, which units does Nod have at GDI base entrance etc
To counter the arties a mix of "everything" will most likely have the best chances:
airstrike the hill (order a 2nd airstrike asap)
3-4 Orcas (with Gunners / Sydneys on 2nd seat) should push out via Ref route
2 Mammoth tanks, 2 MRLS + field rep should push out of GDI base
1-2 APC (patches, gunners, sydneys, whatever inside) push out via river
