From what we've seen of GTVA tactics, they seem to consist of a couple of things and a couple of things only:
1) Jump in at a node, WOMG (not sure if I spelled that right) blow the defenders to tiny bits with the questionable advantage of a surprise attack.
2) Blockade a node, sit there and destroy the oncoming losers with the questionable advantage of the defender.
3) Attack huge ships with a couple of small ships, a bomber wing, and Alpha 1.
This is not sound strategy. Once a node is captured, ships start coming through and do what? They jump to nodes, to capture them, (IIRC not something we see very often) they jump to installations, and blow them up, they form a group for self-defense, or they pull 1), 2), or 3) ( the most likely). In every case, strategy is limited to "we're the GTVA, let's use our superior willpower and blow them away with sheer spirit! TALLY-HO!" The entire reason your side wins is because you're on it, defending allied capships from bomber wings. That's the entire strategic advantage. Neither side is significantly better equipped. Neither side uses any strategy of any sort, except perhaps in Feint! Parry! Riposte! and such.
