Anecdotal only so take with a grain of salt, but it follows the logic that if even attacking forces lose less soldiers they redeploy faster. You can, with some coordination, tip things in the favor of the Allied Forces fairly fast but you can be held up by that one player who wants to solo for exp and make the battle last longer.
It is possible to bring Yagudo Theomilitary Morale down by half in a four hour stretch, just one afternoon, if your goal is to make the Allied Forces win every sortie as quickly as possible and with minimal losses. I can say with great confidence that this effect then cascades for pretty much the rest of the week if you do it on a Sunday or Monday.
It's actually ineffective almost completely to defend any fortification that has no allied defenders presuming you could be somewhere else speeding up a different victory.
