Drenched by well over 100 inches of rain per year, the consequ of a tropical environment can be disastrous to gear. Thick vine vegetation can rip exterior components off passing vehicles, ins can eat through Kevlar, and high humidity and salinity in the rapidly corrode even stainless steels. Vehicles face their own sp challenges: mud and other jungle biomass can degrade perform if not stop a vehicle in its track Having successfully conducted tests of the Stryker and M Resistant Ambush Protected vehicle in the nation of Surinam recent years, TRTC testers were excited to gain permission to te latest upgrades to the Stryker in Panama, a global transportatio where personnel and equipment can arrive fa ÒWe have a better range of different types of roads here logistically you save a good two or three days of shipping this said Julio Zambrano, test officer.

As the vis personnel were returning to Yuma, there was concern that a rel tame El Nino rainy season was in the offing. However, these predi did not come to pass ÒThe difference between the dry and rainy season is night and said Omar Silva, test officer. ÒWhen I returned after being here dry season, I couldnÕt believe it; I couldnÕt recognize it. The soil g soft and the vehicle is so heavy Extremely rugged in the best circumstances, the profile o facilityÕs roads changed as the rains flooded and washed out more and more with each passing d ÒWe had to reclassify certain secondary dirt roads as cross-co all the way,Ó said Zambra Nonetheless, the testers got exactly what they hoped for: unforgiving tropical rainy season on a punishing jungle road c ÒWe expected the vehicle to get stuck,Ó said Silva. ÒWe mad we came up with a good methodology to progressively try to ge vehicle unstuck. That way, you can characterize the performan the vehicle. When the vehicle got bogged down by slick, gripping mud tha formerly a road, testers first attempted to extricate it with a singl pull utilizing the vehicleÕs built-in recovery winch.
