Development
In the late 1950s Czechoslovakia bought license to produce BTR-50s from the Soviet Union. The received documentation was used to develop a new tracked armoured personnel carrier for Czechoslovak army and Ludowe Wojsko Polskie (LWP). The works started in 1958 and first prototype was completed in 1962. After it passed the trials it was accepted and received a name TOPAS.
Because the standard TOPAS vehicle used by Ludowe Wojsko Polskie (LWP) (Polish People's Army) was unarmed, the design bureau of Wojskowa Akademia Techniczna (WAT) (Military Technical Academy) designed a variant armed with a new turret placed centrally on top of the superstructure. Also another TOPAS variant was designed by Wojskowy Instytut Techniki Pancernej i Samochodowej (Military Institute of Armour and Car Technology). The new variant received designation WPT-TOPAS and was a technical support vehicle.

Famous quotes containing the word development:
“On fields all drenched with blood he made his record in war, abstained from lawless violence when left on the plantation, and received his freedom in peace with moderation. But he holds in this Republic the position of an alien race among a people impatient of a rival. And in the eyes of some it seems that no valor redeems him, no social advancement nor individual development wipes off the ban which clings to him.”
—Frances Ellen Watkins Harper (1825–1911)
“For the child whose impulsiveness is indulged, who retains his primitive-discharge mechanisms, is not only an ill-behaved child but a child whose intellectual development is slowed down. No matter how well he is endowed intellectually, if direct action and immediate gratification are the guiding principles of his behavior, there will be less incentive to develop the higher mental processes, to reason, to employ the imagination creatively. . . .”
—Selma H. Fraiberg (20th century)
“There are two things which cannot be attacked in front: ignorance and narrow-mindedness. They can only be shaken by the simple development of the contrary qualities. They will not bear discussion.”
—John Emerich Edward Dalberg, 1st Baron Acton (1834–1902)
