Portable thermobaric rocketry / means of delivering a thermobaric charges
Something I saw the Jagers I briefly worked with using: a series of metal tubes about six inches across, all linked together in a line with a hook at one end, rope linking steps.
Hook top over eg. window ledge, pull, turns into a ladder.
Small, camera-equipped, commercial off the shelf, drones. Feeding images taken at low level back to commanders and troops. Ubiquitous in Syrian urban fighting and very useful, judging by results. Seeing around corners, behind vertical cover, enemy movement, weapons/artillery flashes, and results of own artillery, including fire correction.
The drones used in Syria seem commercial. They don't appear ruggedised and may be regarded as expendable. It could be the way to go - you could get many cheap, short life, drones for the cost of an equivalent made for MoD use.
