From an external point of view, I wouldnt have though there was already so many troops spent.
Players dont know but 10K troops is like, for an average faction of 10-20 players, around 2 months of continual recruitment; if EVERYONE is recruiting, has strategus tickets, none are lost through gold starving, incorrect troop cap, used in defense or just AFK'ing : so its more like around 3-4 (after all errors are accounted for) months of recruitment for an average faction.
Then ABS + CFA/Kapi are quite big so I would say more like a month or two of recruitment, still the war has been on for less than a week. I say GG to all up to now!
It is VERY EASY to lose troops but very hard to recruit them. Hence why to end up with 10's thousands of troops stacked in defense you must be a real turtle
