A few facts that you got wrong:

1) Garissa attack was not a hostage situation. It was a massacre, so there were no negotiations going on since the terrorists were not asking for a chopper and a buss with a tank full of gas. Instead, they were just having a field day butchering and executing students as our army was pretending to secure the perimeter.

2) Modern warfare is essentially Close Quarter Combat. In other words, modern armies generally fight in an urban setting and so it is vital for them to be well versed in CQB/CQC. When you say our army is incapable of fighting Close Quarter Combat, you are actually saying that our army is handicapped, which is not a compliment as may think but a serious flaw.

3) Unless you've been living under a rock, you've probably heard of a bomb shelter. Bombing a building does not necessarily mean job done. In other words, the only way to ensure the warlord in the palace is truly dead is to send soldiers in their to confirm ala Osama Bin Laden. That's the reason why the US Special Forces decided to send real soldiers for that mission instead of firing a SCUD missile from the comfort of Washington.

4) Since you've referred extensively to the US Army consider this: every division of the US Army has an elite team well-versed in all forms of warfare, from Guerilla warfare to Close Quater Combat to Assassination. For instance, instead of the relying on the US Marine famous SEAL 6, the US Army trained their own team of Special Forces. Similarly, the Kenyan Army has it's own team of Special Forces that should actually be much better than RECCe but unfortunately, that does not seem to be the case.

All this talk of the Kenyan Army is not to do this or that is bullcrap. If indeed it is true, then you should be seriously worried because it means our army is so one-dimensional.
