I haven't seen much in the way of modern polymer bullet hoses that eat up your ammunition at the same pace Walstreet eats up bailouts.
I haven't spent weeks without bathing lugging 90 lbs of gear facing constant threats on the verge of dehydration and death in a warzone. Rightly so I don't even dare comment on that, it's not my place , and I know my role and nod my repects to the very members here on the forums as well as all others abroad who have.
Though if for whatever diplomatic or travel agency screw up of a reason I ended alone in a failed state somewhere in the jungle, and had no other option.
Then there is something I could ask for from experience, yes through the back channels and failed firearms control policies of the good ole' US of A, I have had a minor amount of trigger time with some semi automatic version's of the Warsaw Pact's finest. (AKM)
High humidity tropical environment, I would ask for what I know, an 870 express, or an 870 military equivelant, an AKM or preferably an AK 74, and as for side arm, an S&W .40 cal (Solid frame like the SW 99 or police issue model) , because I also am familiar with that platform.
Plus I would look at common ammunition for where you are located at. Can't really go wrong with 12. Gauge 3 inch. or old Soviet Rounds in many areas of the world.
Because let's face it, I don't want something I don't know how to use, or when it malfunctions I am left clueless, learning proper maintance of my weapon as it malfunctions and I am left vulnerable is not the time ask for a manual.
I would have to know by nature the concept of it's mechanism and how to clear ,and return the weapon to firing condition ASAP.
Dehydration, disease and exhaustion are killers if left unattended to, lack of drinkable water can be deadly even in the Rain forest, that being said,
The last thing I would want is some weapon system that is newest and coolest thing in the eyes of prepubescent children who adore it the world over because somebody got a million views firing the faulty prototype on you tube.
Or a 3 D model of the weapon system that looks cool in the latest video game, safety switch and ejection ports being on the wrong side in the game and all. Only for the game's "audience" to never realize there is a reason not one military organization the world over doesn't use the weapon system, mainly because the system is garbage.
Lastly. I ask one thing before I ship out to meet my demise in the Rain forest, at least 3 weeks, solid days spent on the range with qualified instructors with verifiable experience. All the Hollywood images aside, I would like to start over from scratch, learn a few proper marksmanship techniques and principles so when I did screw the pooch in the jungle at least I bite it knowing which end was the dangerous end.
A little recap for those who scrolled to the bottom of my post in fear of the large number of words.
My Choices
870 Express (pistol grip would be nice)
S&W SW 99 .40 Cal or similar S & W platform
AKM or AK 74 with Soviet Issue Sling ( I have a fetish for slings).
