So far. nobody has responded to a few of my points.
1. What will be done with the massive number POWs once we capture them?
2. What moral basis dictates that we must fight a bloodless war? Killing in battle is not necessarily sinful under appropriate Catholic principles.
3. Are Less-lethal weapons using sound able to penetrate walls, flat surfaces, around corners, or must the be used in a direct line of view with no obstacles? What ear protection will the operator need to use, and what will prevent the enemies from using the same ear protection? Sure the enemies can use body armor to try to protect against rifle fire, but it's not 100% effective. If there were a 100% effective protection, then guns would be useless.
4. How will a less-lethal weapon operator get close enough to the enemy to use such a device without being shot?
An easy way to tell the effectiveness of a less-than-lethal weapon is by observing the effect on protestors in the U.S. The protestors, I would argue, are less determined than a jihadi with a suicide belt, and many protestors brave the tear-gas, rubber bullets, tasers, batons, etc. to get their points across. I've also never heard of police using the sound producing less-lethal weapon during a protest turned violent.
Aside from these, the comparison of a military battle vs. Dog the Bounty Hunter is unrealistic at best.
Dog the bounty hunter seeks to capture fugitives, whether a murderer, thief, drug dealer, what have you. These people do not necessarily have the desire to kill or harm anybody. Also, Dog has the advantage of numbers and training. His team of 3-4 agents, trained in self defense, firearms, etc., generally aim to apprehend ONE untrained and often unarmed suspect.
In battle, any number of militarily trained and armed allies will fight any number of potentially equally trained and armed enemies. These enemies have every desire to kill opposing forces, and have the added advantage of fighting in cities and neighborhoods which are endlessly familiar to them.
A major flaw in the arguments of trying to solve problems is this issue of funding. Many people (especially Democrat politicians) think a problem can be solved simply by throwing money at it. This simply isn't the case. Take Adult vs. Embryonic stem cells. I don't know the numbers, but it seems that embryonic stem cell research, which has no successes, has far more money dumped into it than Adult stem cell research, but adult stem cells have a vast range of success with far less funding.
"Bloodless war is no less likely than gasoline-less cars which is evidently and rapidly becoming reality."
The comparison between bloodless war and gas-less cars is absurd. Gasoline-less cars are a long way off, and to imply that our success with alternatively fueled cars is somehow directly proportional to our success with bloodless war is less than reliable.
