Yea, I've never understood the lack of in game wire cutters. Uber Spec Ops Dudes-----Damnit! We've got to cancel the mission; Bob forgot the wire cutters (as the Team mills about dejectedly outside the perimeter fence).
As an aside---I spent most of my career in High Risk Facility Management. Some had solid walls, some had fences. The least secure of them had better security than any of the GRW bases.
For fenced facilities (going as far back as the early '90s)---the fences at minimum would be wired with a vibration sensor (computerized of course), and the inside of the fence was covered top to bottom in razor wire. Snipping/vibrating the fabric would set off an audible alarm in the Ops Center, and ID the section of fence being disturbed. On better systems, the alarm would trigger pan/tilt/zoom CCTV cameras to slew automatically to the disturbed fence section so security could ID the issue, and deploy the proper response (might be internal, or external, or both; responses were always armed). ALL fence alarms were responded to by dispatching multiple personnel to visually check the area (even if nothing was visible on the CCTV system). Alert status was maintained until the responding personnel had verbally cleared the area as secure. Raccoons, cats, marmots, and musk rats were amazingly good at getting through drainage culverts, and the raccoons would climb up and over the fences no matter how much razor wire was on them!).
Fence fabric vibration sensors were complemented by microwave zones, magnetic field influence sensors, and more recently non visible lasers. All of which are activated by anything passing through them (MFIS sensors could be tuned to ignore small objects e.g. cats, raccoons, birds, etc).
Many facilities backed all that up with manned armed guard towers (usually numbered just like the Unidad base towers in GRW) interconnected with intercoms, hardline phones, and radios, and panic button operated alarms. Our guards all had their eyesight checked, so we knew they could see more than 50 ft (unlike the Unidad Guards

). Guard tower weapons ranged from rifles (5.56 or 7.62mm), M240 GPMGs, M249 LMGs, M82 Barrets in a few instances, M110 7.62mm DMRs, and the odd M79 40mm. Security personnel in any tower with a M110 or M82 had to have passed US Armed Forces DMR Qualification courses or their equivalent, and requaled on the company course, scoring 95% or better! Yikes!! All towers with MGs had at minimum; 1200 linked rounds available [for unexpected guests!

Ssssoooo the next time your stealthing into that Cartel or Unidad base, and you find yourself cursing your luck, Team AI, Co-Op Partners.........................it could be worse!
