glider infantry was an ineffective solution to a very real problem
The biggest problem with an Airborne attack is in the first 2 hours, The troops have to be able to assemble it goes like this...
step 1: SGP- small groups of paratroopers
step 2: NCO or Officer join the group and get them moving to an assemablly point
step 3: You now have a mess, several companies, different platoons, and grunts, sappers, antitank, medics, and commo guys, all together with misc. equipment each brought with them.
Thats the first 2-12 hours of a combat jump depending on how scattered the drop was...from there you assembal into what you see above it may take a full 24 hours to account for everyone in a combat situation, as for equipment who knows???
Glider Infantry was an attempt to aviod this and put organized immediate force on the objective with little to no warning:
look at where glider infantry was used, cross roads, bridges, ect...they were not paratroopers think of them as the equal to todays air assualt from choppers.
The difference is you are not trying to put an entire division on the ground behind enemy lines, just a company or two to take a hardened objective quickly and intacted.
BTW that is almost exactly how a modern regiment in the 82nd looks today the motor company is now called Delta's and there is a platoon of MP's and Engineers in each regiment
