Well, I.S. never seems to be invincible. Once again, I refer to Chifuyu's implication about her being heavily injured in her sortie as White Knight, meaning all those pesky machines she destroyed does its wonder.
Now that I.S. being an integral part of Military, the warfare doctrine will be updated. Discounting the possibility of military already have anti-I.S. weapon on their own, I believe military might able to take one or two I.S. with conventional force. But of course, there'll be lots of death because few people is really merciful as Chifuyu.
In Sacred Twins, there will be a scene where a reckless PT member is knocked out instantly by means of 127mm conventional Shell.
