Feudal Japanese firemen would scale high ladders to use them as a high vantage point to observe the direction and progress of a conflagration. By placing something such as a video camera on a ladder it is possible that a ladder could be used as a sensor mast for the vehicle or a dismounted unit.
A google of military ladder turned up these interesting examples.
The boarding ladder with a hook at the end reminded me of the ninja climbing poles, which resembled rakes. Adding rungs out from the sides of such a pole is a sensible innovation. The Apollo Cobra urban ladder resembles a big letter I with cross pieces at the end that can be rested on the ground or against a wall. Supposedly both types are modular and can be lengthened easily. Could we create a ladder that incorporates the merits of both? Probably. If we are considering military applications of ladders talking to the local fire department about hook-ladder technique and design might save a lot of time.
There are other considerations to the military ladder. It may be used in the dark and under stress, so if possible it should be capable of being used either way up. Ladders may also be utilized to bridge gaps in both the urban and rural environment so a design that can be safely walked across by an equipped infantryman needs to be considered. Rungs must be splaced so the sole of a boot contacts at least two with each step.
This article shows a design of loading ramp that can be used as a sand-ladder. With the spacing of the rungs optimized we could construct a device that can be used as a ladder, sand-ladder or a bridge for both infantry and light handcarts.
