This video by Ted from Line45 outlines seven essential calibers Americans should stockpile to prepare for potential ammunition shortages, citing patterns observed in past events like the 2020 crunch. The advice focuses on calibers that disappear first due to high demand from various user groups, supply chain vulnerabilities, and production limitations. The instructor emphasizes maintaining separate stashes for training and defensive ammunition for each caliber.

This video provides a detailed comparison of several 5.56x45mm NATO ammunition types used by the US Navy, focusing on their terminal ballistics and penetration capabilities. The Mark 255 Mod 1, featuring a compressed copper polymer core, is highlighted for its rapid fragmentation and potential for large wound channels, while the M855A1 is noted for its extreme penetration. The M855 Green Tip and Mark 262 Mod 1 are also tested for comparison.

This video tests the ballistic resistance of a sledgehammer against various calibers, from .22 LR to .50 BMG. It demonstrates that even smaller rounds cause superficial damage, while larger calibers like 7.62x39mm and 5.56mm create significant dents and fragmentation. The .50 BMG round causes the most substantial damage, but the hammer remains intact, suggesting a high degree of ballistic resistance.

This video tests the bullet resistance of a sledgehammer against various calibers, from .22 LR to .50 BMG. The sledgehammer demonstrates significant resistance, with no caliber achieving a complete pass-through. Notably, even larger calibers like 7.62x39mm and 5.56x45mm NATO caused significant denting and bullet fragmentation, while the .50 BMG created a substantial divot. The experiment concludes that a sledgehammer is effectively bulletproof against the tested rounds.

This video debunks the widespread rumor that Glock has released an AR-15 for the general public. It clarifies that the 'Glock AR-15' refers to the GR-115 rifle, selected through a UK National Police Primary Carbine Tender. The content emphasizes that this is a procurement process, not a commercial product launch, and explains the nuances of UK procurement frameworks. It highlights the lack of official US product announcements from Glock and discusses the complexities of entering the competitive US rifle market.

This video evaluates the FN SCAR 15P as a potential truck gun, comparing its 'sci-fi' refinement to the 'caveman' brutality of the Micro Draco. It highlights the SCAR 15P's compact size, maneuverability, and familiar AR-like controls, while acknowledging trade-offs in blast, cost, and velocity loss from its short barrel. The discussion emphasizes choosing a truck gun based on individual priorities, training, and tolerance for compromise.

This video demonstrates universal shooting standards, emphasizing under one-second engagement times from high and low ready positions. It showcases drills like the Bill Drill and a 3 Body, 2 Head sequence, highlighting efficient weapon manipulation and accuracy with a custom AR-15 build featuring an EOTech optic and GBRS Hydra Mount.

This guide, based on instruction from DJ Shipley of GBRS Group, details the critical importance of proper posture while wearing body armor. It emphasizes standing upright and squaring plates to the threat to maximize ballistic coverage, contrasting this with the dangerous practice of leaning forward, which can expose vital areas. The instruction highlights techniques for effective protection in tactical scenarios.

This GBRS Group video emphasizes mastering carbine reloads by prioritizing proper technique over raw speed. It highlights the critical importance of a firm, forward support grip (like a C-clamp) for weapon control during CQB and high-stress scenarios, warning against sacrificing fundamentals for fast 'par times'. The correct sequence involves sending the bolt, moving the support hand forward, establishing a solid grip, and then re-acquiring the target.

This video showcases an advanced tactical training session led by an expert with former Tier 1 Special Operations experience. The drill integrates live fire range exercises, high-intensity physical conditioning on an Echo Bike, and close-quarters battle scenarios, all while monitoring biometric data to simulate combat stress and optimize performance.
