1. Assess the Likely Threats
   
   • If your location is only at risk of basic handgun fire, Level 1–3 may be sufficient.
     
   • If rifles are a realistic risk, you’ll need at least Level 4.
     
2. Consider the Environment
   
   • Corporate campuses and private facilities often choose handgun protection (Levels 1–3).
     
   • Military bases, ports, and critical infrastructure lean toward rifle protection (Levels 4–8).
     
3. Balance Security and Cost
   
   • Higher levels mean heavier, more expensive materials.
     
   • It’s important to match your budget to actual risk.

Practical Advice Before You Buy

When buying a bulletproof guard shack, the right UL 752 level depends on the threats your security team may face. Handgun protection (Levels 1–3) may be enough for many businesses, while rifle protection (Levels 4–8) is necessary for high-risk environments. 

Consulting with a manufacturer or security expert will ensure you get the right level of protection without overspending.
