How do you define immobility? Is it its ability to emplace and displace within a short span of time so that it can rapidly relocate to avoid counter fire? What would it be relative to? A similar ULH? or something that has a design weight margin 2 or 3 times of it?
Emplacement and Displacement Requirement for the Triple Seven -
TheLW155 (a single weapon) shall be emplaced and ready to fire (weapon is laid, at least one reference point has been established, one round of ammunition is ready to be loaded, and communications with the Fire Direction Center (FDC) are established) by no more than five crewmen including the gunner and four other cannoneers in three (threshold) to two (objective) minutes or less, after the prime mover has stopped in position.
Once emplaced,the LW155 (howitzer, crew, prime mover, and associated equipment) shall be loaded and prepared to immediately depart the current location, by no more than five crewmen in two (threshold) to one (objective) minute
Once in theater it can relocate via a medium transport truck (MTVR or FMTV in US services) and the emplacement and displacement times are based on moving it via that route. The physical weight of the weapon system and the munitions is kept low on account of a 4300 kg system (4200 kg weapon + 90 kg generator) which allows lighter trucks to move it. Fording requirements were kept at par with those of the trucks the two services were going to use to move it, and the speeds were also kept fairly high (88 kph on road, 56 kph on secondary roads, and 24 kph on cross country roads). I guess if you are comparing it with heavier guns like the Bofors that have an APU however those are much heavier (nearly 3 times) and moving them cross country at the same speed would probably pose a harder challenge using a similar sized vehicle.
Now consider where these guns are going to be operating..up in the hills, given the terrain, altitudes the enemy will also have mobility issues with its guns, radars and command and control. China's has also developed an ULH presumably for a similar environment and with mobility in mind. Keep in mind that based on IA needs the M777A2 is very much a niche player, to be used in theaters where mobility and transportability is an important factor. The requirements for heavier, more automated, longer ranged guns are much much higher and will be met almost exclusively by indigenously developed and produced systems.
