In reality i'm sure some people are aware that some militaries & even in situations outside of which "boosting" someone is more plausible that going around an obstacle, such as low walls, high barriers, etc.
The ability to make a human ladder with one person wall squating with their back to the wall, as someone else climbs up on their knees/shoulders to get a "boost" could in many ways help out in gameplay. Smookie last I checked had implemented such before he went on to work at BI, in the future, mostly for urban combat scenarios it should be a nice feature to have. {F17090}
