Obama sending 100 troops to war with Lords Resistance Army in Africa

Obama is dropping 100 US troops in unfamiliar territory against an entrenched army of 3000 who have been fighting operationally since 1987, and they are religious fanatics to boot. This is a recipe for disaster.

According to Wikipedia, Lords Resistance Army LRA was formed in 1987 and until about 2007 it was engaged in an armed rebellion against the Ugandan government. It is led by Joseph Kony, who proclaims himself the "spokesperson" of God and a spirit medium, primarily of the Holy Spirit, which the group believe can represent itself in many manifestations.

Putting a single boot on the ground is considered a military action. If the enemy has an army of 3000, why did Obama choose to send 100 troops? Why not send 1000 troops, wipe the villages clean of this rabble, and be done with it? 100 troops is just enough to make sure the world believes we are instigating a military action, but not enough to win. I am all for stopping this group of degenerates, but sending such a small fighting force is not the way to do it. What does Obama expect will happen? Does Obama want our fighting force to lose?
