用李 - Yes people operating in the howizter need to observe operational safety and soldiers need to look out for one another's safety.
This Primus are specially designed to operate in Singapore environment that need to negotiate bridges, road, tight terrain that are specially suited to operate in our terrain. The chassis is a US-designed.
This type of self-propelled howitzer work very effectively in combat as operated by US, UK, Japan, Russia - where it provide arty support in tandem with the armor operation (as compared to conventional arty - that are not so mobile). And its firing range is 30 km - that suit very well in supporting armor - which can help to soften the ground before armor move in.
We cannot buy other howizter in any market because they are too big and too heavy - and our roads cannot take it and will sink - and it will get stuck in bridges, road, building or forest. The 30 ton (versus 50 ton) and the 3 metres length allow us to maneouver our constraint here.
The ammo loading is semi-automatic and the firing control system is fully automatic.
At all times, crew should keep clear of the 2 danger points.
The Primus automatic targeting system using datalink and GPS - fully integrate and share info. with all other units - that can launch seamless simultaneous attack with other formation - and give us a decisive victory --- neutralising arty, mortar, multi-barrel missile launcher or armor units targeting us before our armor move in.
Without this self-propelled howitzer, our troop, our armor, our buildings will be in peril to adversary arty, mortar, multi-barrel missile launcher or armor units - as we cannot strike them at long range - and we will come under saturated arty, mortar, multi-barrel missiles attack.
In fact the Primus is the one of the most advanced type of self-propelled howitzer - but crews need to observe safety operation guideline.
Thus soldiers operating in the Primus need to look out and observe all safety precautions when operating the Primus.
"Safety is alot of common sense" --- and all soldiers must be mindful all the time in major exercises or in operating military assets - to look out safety for ourselves as well as for fellow soldiers around us.
