Will post a reply later in the IN thread to keep this thread on topic and because there are several things that you got wrong.
Which is plain wrong buddy and your pics even show it!
Why does the Chinook need to carry these 2 Jeeps externally? Because it can only carry a single of them internally, just like our Mi17:
A Mi 26 on the other side can carry up to 20t internally or externally and has a cargo hold that is 15m long, now a Humvee weighs around 2.5t and has a lenght of around 5m. That means, a single Mi 26 must be able to carry 3 x Humvees internally + at least 2 externally.
Other payloads in war times could be:
- a towed Bofors howitzer externally, while the truck that tows it internally!
- a BMP IFV externally
- a wheeled APC internally or externally
- support trucks with ammo internally or externally
- cranes or heavy machinery to re-build airstrips or roads
...in all these roles, the Chinook will be next to useless, because it can't offer similar capabilities, especially internally!
The Ch 53 would indeed be the much better choice, but the older versions are out of production and the K version under development only.
The best possible choice would have been CV22s now and CH53K later, because IAF would have added a good aircraft for special ops, that also can carry higher loads than our Mi 17s and has a rear ramp to unload cargo or troops at high altitudes, while the CH53K, latter could have taken the heavy lift roles, in IAF as well as IN LDPs.
