Indeed it is, as was the 155mm towed howitzer that served in the RCA for ten years. As an officer cadet I was a member of a gun detachment on several occasions and it is brutally hard work, but it can be done. (I also was put in charge of bringing the M109s in the RCSA Shilo into service in 1968 and then trained several hundred people ranging from full colonel to "TQ 3 gunners" on it, and can get misty eyed about SPs if you plie me with strong or even weak drink.
As for your other argument re the threat, could you come up with a scenario that fits your paramaters? Anything is possible, I guess, but current projections suggest that your possible threat is unlikely.
And last, I had a long interview with the gentleman who was the BSM E Battery on TF 3-06 (and picked up a MSM and a MiD) on the tour. He had experience with the Pz H 2000 as a platoon of Dutch SPs was attached to his battery during Medusa. According to him, there were some serviceability difficulties with these howizers during the operation - no slur intended towards our Dutch allies - as these were equipment related.
Let's not turn this into a dick measuring contest and agree to disagree.
