There's two types: The SPG (Self Propelled Gun) and the split trail (towed field gun). Both were used extensively in Vietnam. Any website on artillery will show the two. If you want to see some photos of the 155mm field pieces in action, search for Firebase Vandergrift in 1971, during the Lam Son 719 operation (invasion of Laos).
Firebase Vandergrift (also called FSB for Fire Support Base) had a battery of 155mm field guns there (6 guns).
Post Vietnam US Army batteries contain 8 guns.
A "155" artillery round is a 155 mm (diameter) shell, approximately 6 inches. Examples of guns that fire this type of shell are the 155 mm M114 howitzer, developed just before World War II.
there is direct fire so the fire man can see the target and the observatory controled fire and that range depend on weapon the range may be more than 30 km
Depends on the cannon. The field artillery used in the American Civil War could shoot about 1000 meters. The "Paris Gun" used by Germany in WW 1 could shoot 81 miles. The present day US 155 mm howitzer can shoot 25 miles with special guided ammunition.

Too broad to answer. You have to define 'gun". A 155 mm howitzer weighs about 7 tons. A double barreled Holland & Holland .600 Nitro Express weighs about 21 lbs.

Hearing loss WILL happen by firing any gun without protection. Of course the level of hearing loss that will occur will depend on the gun and for how long and how frequently one gets exposed to it, but firing ANY type of gun without ear protection is not safe.
87% of 155 = 87% * 155 = 0.87 * 155 = 134.85
