We're just kinda holdin' them in our mouths as we're opening fire back. And we're running down the alleyways, take big ol' bites outta the ice cream cones, sat there, chew it."

"Lessons Learned:
- Good, well-trained men will die in combat. NOTHING REPLICATES THIS.
- 'Team' must be solid BEFORE deploying.
- Inside (buildings) is better than outside (buildings). Image 2/8
- Live fire exercises build cohesion and confidence. This took away the initial fright of enemy fire.
- Warrior mentality is CRITICAL!! TRAIN FOR WAR, NOT NTC, JRTC, etc.
- Everything must be related to combat. Image

If there is a lack of precision guided munitions large artillery shells, rockets, bombs & missiles are not entirely accurate & can cause extensive collateral damage. Of course, the Russians have demonstrated this time & again in the Russo-Ukrainian War:
