Sending more troops to what end? Is there going to be an increase in the intensity of fighting like what Mattis is doing to ISIS in Iraq (not allowing the enemy to flee the battle field - total annihilation)?
Our troops are not doing the fighting there.
Probably to get enough firepower to bring it to a conclusion. That MOAB back in April did some serious damage to both ISIS and our fake Pakistani “allies” who were in Afghanistan protecting the enemy. Some unidentified commandos came in after the bomb and sorted out whatever was left.
Our extra troops may be as much a command role as combat. People likely have no idea about how many Muslim allies are doing heavy urban fighting for us in Mosul and Raqqa. No ISIS are taken prisoner.
